Jeffrey’s “Folder Watch” Lightroom Plugin

This plugin is a feature-rich alternative (or supplement) to Lightroom's built-in tethering and Auto Import, and also attempts to make up for Lightroom's lack of an auto-export facility. It allows you to run a continuous scan of select folders on your hard disk in the background, automatically importing new images in place, or first moving/renaming if you like.

It can scan an individual folder, a list of folders, or whole trees of folders.

It also allows for automatic processing of imported images, and also automatic export, creating a fully-automatic end-to-end processing system.

As a special case to enhance Lightroom's built-in tethering, it can apply special processing to images that have been recently added to Lightroom.

This plugin works in Lightroom Classic, and older versions as far back as Lightroom 4 (though some features depend on the version of Lightroom).

The same download works for both Windows and Mac. See the box to the upper right for the download link (in orange) and installation instructions.

Configuration and Use

The plugin is configured in the Plugin Manager:
The dialog shown is as of version 20180503.126; the current version of the plugin is 20201017.151.

When the Enable Scan checkbox is checked, the scan runs continuously, even after the Plugin Manager has been dismissed.

Scan-Related Configuration Items

Folders to watch  —  A comma-separated list of folders the plugin should scan for new images. Non-absolute folders are relative to the catalog folder.

See the Common Scenarios section for guidance here.

Also watch subfolders  —  If checked, the scan also descends into all subfolders of the folders listed.

Frequency to check  —  The scan takes some of your computer's resources, so it's not prudent to have it scanning nonstop; this indicates how long a pause should be made between scans.

New images only  —  If checked, images found in the first scan are not imported. This is perhaps useful when tethering and are interested only in new images going forward.

Ignore suspected duplicates  —  Ignores (does not import) new files that have the same filename, byte size, and pixel dimensions as a photo already in the catalog. (If a catalog photo is currently offline, that is, its master file is not currently available, then the byte-size comparison is not included in the decision.)

Filenames to consider  —  Lets you include or exclude filenames that match a filename pattern like *.jpg.

Special rules for when the provided pattern includes a slash: in this case, the pattern is matched against the full path of the file being considered. To exclude files in a sub-folder named junk, for example, select exclude names matching pattern and enter a pattern of /junk/. To exclude files in any folder that has junk in its name, use a pattern of junk*/ or /*junk.

(The special rules about folder patterns make sense only when Also watch subfolders is turned on.)

File size to consider  —  A sanity check to avoid too-big or too-small images.

File unmodified for  —  If the plugin were to try to import a file as it was being written to disk, Lightroom would get only a partial file, resulting in errors. To help avoid this, the plugin waits until the image file hasn't been updated for some time, in hopes that doing so will ensure the write has fully completed.

Read-only images only  —  Enabling this has the plugin ignore writeable files, considering only read-only files. The lock image feature on some cameras can result in a read-only file on disk.

Special tether support  —  This special option is explained below.

Move/Rename Configuration Items   

Just before a file is imported, you can have the plugin move it to a target folder, and rename it as well.


If you enable the file-move option, the plugin moves images it finds into a folder you specify.

In specifying the target folder, you can use many preset template tokens, though most that refer to photo metadata are not available. However, tokens that refer to the capture time of the image, such as {YYYY}, are available.

You can also use tokens that refer to the master image file (in this context, the file to be moved/renamed, prior to move/rename and import), such as {FileYYYY} for the file's creation year, or {FolderName} for the name of the folder that the file to be imported was found in.

In writing the target-folder template, sub-folders can be separated by either kind of slash (forward or backward).

Optionally, you can then append the name of the watched folder (test2 in the screenshot example above) to come up with the final target folder. (This is the same as using {FolderName} at the end of the move-to path, or at the beginning of the rename-to path.)

For example, if you have the plugin watch folders named Main Shooter, Sub Shooter 1, and Sub Shooter 2, enabling this option would have images moved to the appropriate sub-folder (Main Shooter, Sub Shooter 1, or Sub Shooter 2) of the destination folder you specified.

Additionally, you can have the plugin preserve any folder structure found under the watched folder, replicating it within whatever target folder the above steps resulted in.


The rename to field also accepts preset template tokens: tokens accepted are the same as those mentioned in Moving above.

For example, a rename to value of {YYYY}-{DD}-{MM}/{Filename} has new images moved to a subfolder (of the target folder computed by prior steps) based on the image capture time.

Or, you might use a rename to value of {yyyy}{dd}{mm}-{hh}{min}{ss}-{Filename} to prefix the current date/time to the image filename, and then place it within the move-to folder.

You can use either kind of slash (forward or back) to separate sub-folder names.

The plugin always ensures that the file extension remains the same across any move or rename, so you don't have to worry whether you specify a file extension in the rename to field.

You can specify that filenames should be rewritten to a sequence by including ### in the filename, using as many # as you want digits in the sequence. For example, you might use photo#### to have your files named photo0001.jpg, photo0002.DNG, etc. (the file extension will be maintained from the original file on a per-image basis). It's a pretty smart sequencing system, and always picks up from the filename with the highest number in the # location.

The plugin will never overwrite a previously-existing file; conflicts that arise are resolved via renaming as with photo-2.jpg, photo-3.jpg, etc.

Import-Related Configuration Items   

Show splash dialog  —  If you want to be alerted when an image is auto-imported, enabling this has a small dialog pop up for a few seconds. This can be useful particularly when Switch to photo is enabled and you intend to be using Lightroom interactively, to avoid keystrokes suddenly going to the new photo.

Apply develop preset  —  A develop preset you've previously saved can be automatically applied.

Apply metadata preset  —  Same with a metadata preset.

Add keyword  —  A keyword can be automatically added.

Set star rating  —  You can set the star rating.

Set color label  —  And the color-label text (which can be one of the defaults like red, or anything else you like). Once you've got something typed in the text field, the checkbox can be checked.

Set title  —  The image title can be set. You can use template tokens for dynamic text, e.g. Copyright {YYYY}.

Set caption  —  The image caption can be set, here also with template tokens.

Switch to photo  —  If enabled, upon each import Lightroom will switch to the Library view for the new photo's folder, and the new photo will be selected.

If you happen to be typing something into Lightroom when this suddenly happens, what you type will be taken as keyboard-shortcut commands for Library, which could be very bad, so enable the Show splash dialog option if you'll be using Lightroom interactively while the scan runs in the background. The splash dialog kills the keyboard input, giving you a few free seconds to realize what's happening and to stop typing.

Build Smart Preview  —  The Smart Preview can be made automatically.

Add to standard collection  —  Newly-imported photos can be added to one of your library's collections. This can be useful for many things, including automatically sending imported images to the web or your iPad via Lightroom mobile.

Add to Publish collection  —  Newly-imported photos can be added to a Publish collection.

Publish this collection  —  A specific publish collection can be automatically published with each new import, or, optionally via the also publish other collections in its Publish Service checkbox, all collections within the publish service are published.

This option is distinct from the Add to Publish collection because that option works only with non-Smart publish collections, but you may well have a smart collection that you want to publish automatically.

You can choose any publish service for each of the last two options. Choosing an uploader service (such as to Flickr, PicasaWeb (G+), or Tumblr, among many others) can allow for automated from-camera-to-the-web processing.

Alternatively, for local output (or to Dropbox, network disk, etc.), perhaps consider my Folder Publisher and Collection Publisher plugins. Publish Services from other developers should work fine too.

Special Tether Support  —  this option is discussed below.

Advanced Flexability: Execute Your Custom Lua Script

Those with the technical ability to program computer code in the Lua language can tap into that flexibility to perform custom actions as each photo is imported.

Your Lua script, which must be in a *.lua file, is executed within a simple environment that includes the variable photo, which is the LrPhoto object representing the newly-imported photo. The script can access information about that photo, and if it wishes to make changes to the photo can return a function that makes those changes. If such a function is returned by your script, the plugin will then execute it when Lightroom allows catalog updates.

As a simple example, here's a script that sets the star rating of newly-imported photos to 3 only if they currently have no star rating:

if not photo:getRawMetadata('rating') then
   return function()
             photo:setRawMetadata('rating', 3)

The simple environment in which the Lua script is run includes the basics from the standard Lua environment (e.g. the string and table libraries), and also some namespaces provided by the Lua SDK, such as LrDate and LrPathUtils.

It also includes the function log(), which dumps its arguments to the plugin log (see the upper-right section of the plugin manager), and printf(), which is a standard formatted print to the plugin log.

Note: Lightroom uses Lua version 5.1.

Special Support for Lightroom's Tethering

Tether support was added in version 20140721.82 (July 21, 2014), and should be considered beta.

This plugin main purpose is as a replacement for Lightroom's integrated tethering support, because Lightroom's tethering offers very little in the way of advanced workflow support.

As such, the plugin's main purpose is to find image files that have not yet been added to the current Lightroom catalog, import them into the catalog, then apply the various workflow support features selected by the user, such as setting a develop preset or adding to a publish collection. In this context, it's presumed that one uses some third-party solution to get the image files to appear on your disk, such as third-party tethering software, Dropbox or the like, an FTP server, or even an Eye-Fi memory card.

However, the plugin does offer a way to work with Lightroom's integrated tethering support, to perform the aforementioned apply the various workflow support features selected by the user step on files that found their way into Lightroom apart from the plugin (presumably via tethering) since the plugin started its scan.

To use this special support, have the plugin watch the same folder that Lightroom's tethering support is depositing files, and turn on the

Enable the Upon Import of a New Image processing for all relevant newly-added images

option in the plugin. Then start the plugin scan, and then start your tethering.

When you start the plugin scan, the plugin will first take the time to note what images under the watched folders are already in Lightroom. Since they're in there before the scan and tethering starts, the plugin knows not to touch them later. (If the plugin didn't ignore pre-existing Lightroom photos in this way, it would apply all the after-import processing to all the images, every time, which could lead to disaster.)

Then the plugin will scan the folders as often as you've told it. If you're using Lightroom's tethering, new files that the plugin comes across will likely already be in Lightroom (having been imported by the tethering unit at the same time it created the image file), but it's perhaps important to remember that any time the plugin finds a file that is not already in Lightroom, it'll import it into Lightroom and perform the after-import steps.

Anyway, what'll happen if you're using tethering is that the plugin will find the new file is already in Lightroom. It'll check against the list of photos it made when it started its scan, and realize that indeed the photo is new since the scan started, and because this special tethering-support option has been enabled in the plugin, the plugin will go ahead and apply the after-import selections such as applying a develop preset or adding to a publish collection.

This is the only situation in which the plugin processes an image that it didn't itself import.

In this scenario, an image can exist be added to Lightroom by the tethering unit and sit there for some time before the plugin gets around to the after-import processing. How long depends on the frequency to check setting, how much scanning the plugin has to do (few files or logs?), and the timing of the tethering with respect to the scan.

Common Scenarios

The plugin can scan folders that are not part of your Lightroom catalog, folders that are part of your Lightroom catalog, or both. It can move/rename files or not, as you see fit. People use the features of this plugin in all kinds of crazy combination, but here are there common scenarios to consider:

  1. Using a drop-off folder outside of Lightroom

    If you have a third-party application depositing files to a drop-off folder (or a drop-off folder that's getting new image files somehow, such as a Dropbox folder being fed externally), you can watch that folder with this plugin, and use the plugin's file-moving options to shuffle the files into a folder that Lightroom knows about. The plugin will then add the image to Lightroom.

    In this scenario, the drop-off folder is generally empty except for when a fresh file has been deposited but not yet processed by the plugin. This is the most efficient scenario.

  2. Feeding a Lightroom folder with a third-party application

    This scenario is similar to the one above, except the folder that new image files are deposited into (via the third-party app, Dropbox, etc.) is already a folder that Lightroom knows about. In this case, you'd probably not want to use the plugin's move/rename options, but just have the plugin scan a folder that Lightroom knows about, adding new files to the Lightroom catalog in place.

    In this scenario, the plugin is acting like an automatic (and richly-featured) Synchronize Folder replacement.

    Because files are not shuffled out of the watched folder, this scenario can become inefficient as the number of images in the watched folder becomes large. One does not generally want to apply this scenario to the entire Lightroom folder hierarchy, or any hierarchy with more than a few thousand photos, because the scan time could get inconveniently long.

  3. Feeding a Lightroom folder via Lightroom's tethering or auto-import features

    This scenario is similar to the second one in that the plugin watches a folder that Lightroom already knows about, but it differs from the other scenarios in that it can work with photos that are added to Lightroom via Lightroom's tethering or auto-import features. Normally, this plugin completely ignores any image that it doesn't add to Lightroom itself.

    This special scenario is available only when explicitly enabled via the option described in the section on tethering. In this scenario, files found during the scan to have been added to Lightroom (by something other than the plugin) since the plugin's scan started are not ignored, but instead get the after-import processing configured in the plugin.

    This can be useful with tethering to do additional processing that Lightroom's tethering doesn't allow, such as adding a photo to a collection or exporting via Publish.

    This scenario is more resource-intensive than the scenario above, so you probably don't want to apply it to a folder with more than a few thousand images (though trial and error will show you if/when things begin to bog down).

The three scenarios are not mutually exclusive... it's possible to have them all apply at the same time (though such a need would be quite esoteric, I'd think). Anyway, they're just common use cases; once you learn what the plugin can do, you can apply it to your needs as you see fit.

Note that regardless of the scenario, there's a special case built in to the scanning: any subfolder named picasaoriginals is ignored. Such folders are a byproduct of Google's old Picasa software.


This plugin is distributed as “donationware”. I have chosen to make it available for free — everyone can use it forever, without cost of any kind — but unless registered, its functionality is somewhat reduced after six weeks.

Registration is done via PayPal, and if you choose to register, it costs the minimum 1-cent PayPal fee; any amount you'd like to add beyond PayPal's sliding fees as a gift to me is completely optional, and completely appreciated.

Note: a Lightroom major upgrade, such as from Lr6 to Lr7 (or the equivalent under the hood for the Lightroom Classic subscription) de-registers the plugin in the upgraded version, so if you want to maintain registration, a new ($0.01 if you like) registration code is needed in the upgraded version. It makes for a hassle every couple of years, I know. Sorry. See this note for details.

For details on plugin registration and on how I came into this hobby of Lightroom plugin development, see my Plugin Registration page.

20140718.80 Using a {LUA} token in the file-renaming template caused a crash.

When moving an image from a watched folder, you can now preserve the name of the watched folder in the move destination, and also preserve in the move destination any folder structure that had been in the target folder hierarchy.

Plugin wasn't recognizing the existence of a re-created "folders to watch" target if the name didn't change.

Fixed an issue with Creative-Cloud revalidation.


Lr5.5 and later Creative-Cloud installs can now revalidate themselves if needed.

Fixed an "invalid option '%_' to 'format'" crash.

Turned off most debug logging if the "enhanced debug logging" option in the Plugin Manager is not enabled.


While writing the docs for the new file move/rename feature, I came up with a great(?) way to automatically do sequences. You can now rename to something like "photo-###" to have a sequence number filled in (in this case, a three-digit sequence number).


Fix a bug that would cause certain folder trees to be ignored in certain situations on OSX(!)

Added a move/rename feature.

Moved the status text next to the "enable" checkbox, and made the status text more clear and verbose. Added a countdown timer for the next scan.

20140121.63 Added more debug logging to track down why some scans don't seem to be happening.

Ignore corrupt develop presets instead of crashing due to them.


On OSX, don't consider files/folders whose name begins with a dot (which is the traditional Unix way to mark certain kinds of system-support files that should normally be hidden).

Wasn't properly skipping the "picasaoriginals" folder; is now.

20131112.60 Bumped up the maximum file size to import to 20 gig.

Fixed that plugin could fail to work when Lightroom started in "Select Catalog" mode.

UI was a bit cramped on Lr4 and earlier.

20130306.45 More tweaks
20130304.44 Tweaks for per-catalog setting handling.
20130303.43 In Lr4, the "restart on launch" setting is saved per catalog.
20130209.42 More build-system maintenance
20130206.41 Tweak for my registration system

Added the ability to apply Develop and Metadata presets upon import.

Now can have imported photos added to an “Imported by jf Folder Watch Plugin” collection.

Dialog was getting crowded, so split the watch control from the plugin info.

20120913.38 Fixed a end-of-scan "bad argument #2" bug.

The plugin normally won't try to import a file that has been modified in the last five seconds, but now that five-second threshold is exposed as a setting. Also, on Windows, it won't try to import a file it can't read (because a file being filled by another process disallows us to read it.)


Added min/max filesize settings, so that files outside that range are simply ignored.


Ignore any folder with "picasaoriginals" in it.

Added the ability (in Lr3+) to switch directly to an image when it's imported.

20120608.34 Fix an "attempt to perform arithmetic on field" error.

Update to handle the Mac App Store version of Lightroom.

Don't try to re-import master images that Lightroom has a problem with (because they are corrupt, for example) unless the file actually changes. Upon error, report the full path along with the error.


Better report fundamental master-image-file errors that Lightroom encounters.

Tweak for Lr4.1RC2.

Enhanced the send-log dialog to hopefully make reports more meaningful to me, yielding, I hope, the ability to respond more sensibly to more reports.

20120330.31 Update to handle 4.1RC
20120309.30 Had broken registrations in Lr2; Update to the debug logging to better track down timing issues that might arise.
20120304.29 More prep for Lr4.
20120216.28 Added some extra debug logging, and more work for Lr4. Also end a current scan early if "watch" is disabled.

More on the march toward Lr4, including upheaval in the code to handle Lightroom APIs being discontinued in Lr4.

20120114.26 More tweaks for Lr4b

Update for Lr4 beta: explain in the plugin manager that the plugin can't be registered in the beta.


Had issues with the registration button sometimes not showing.

When doing a plugin upgrade, offer the ability to flush all the old copies of the plugin.

Added a system-clock check and reports to the user if the system clock is more than a minute out of date. An incorrect system clock can cause problems with various kinds of communication and authentication with some of my plugins, so I've just gone ahead and added this to every plugin.

20111020.23 Now imports video as well (ones that Lightroom supports), and tidied up the list of image file extensions to try to import to better match what Lightroom understands.
20110714.22 The remote-filesystem-time-is-off detection wasn't working when there were multiple folders to scan.
20110525.21 Some windows folders couldn't be scanned... think I've got it fixed now.
20110520.20 You can now select multiple folders to scan.
20101017.19 The whole display was getting cut off at the right sometimes.
20100829.18 Made the revalidation process much simpler, doing away with the silly need for a revalidation file.
20100820.17 Discovered a bug in my plugin build system that caused horribly difficult-to-track-down errors in one plugin, so am pushing out rebuilt versions of all plugins just in case.

Added all kinds of enhanced folder-scan logging when Enhanced Logging is turned on, to try to track down some issues.

The plugin now tries to detect and adjust for a remote file system having a different clock than the host system.

Added code to allow plugin revalidation after having been locked due to a bad Lightroom serial number.

20100625.15 Yikes, shaking out some more build issues.
20100624.14 Discovered a nasty build bug; pushing a new version in case it affects this plugin.

This version can be registered in Lightroom 3. It can run in Lightroom 2 or Lightroom 3; it does not work in the Lr3 betas.

It uses my new registration system when run on Lightroom 3, which avoids some of the silly issues of the old one. Please take care to note the details on the registration page: use of this version (or later) of the plugin in Lightroom 3 requires a new registration code, even if you had registered some older version of the plugin.

20100516.12 Update for the Lr3 beta.

Completely changed how the one-click upgrade applies the newly-downloaded zip file, in the hopes that it'll work for more people. Rather than unzipping over the old copy, it now unzips to a temporary folder, then moves the old folder out of the way and the new folder into place. Prior versions' folders are now maintained (with the version number in the folder) in case you want to revert a version; you may want to clear them out from time to time. Of course, it won't take affect until you try to upgrade after having upgraded to or beyond this version.

Wholesale changes that attempt to honor the user's locale settings for numeric display (e.g. Europeans writing 3,14156 for pi). I've probably missed some spots, so let me know if you find some.

Fixed up some UI confusion that happened sometimes if the plugin was not enabled and there was no valid folder to scan. A few other small UI cleanups, and a fix that caused the plugin to abort sometimes in LR3b

20100111.10 Re-import a scanned file if it has changed (size or create/modification date). Thus, if you move a file out of the scanned tree from within Lightroom and later add another file with the same name, it'll get imported. I also now report only the number of files scanned each time; folders are not included in the scan count.
20091221.9 Added some heuristics to avoid importing a file that's still being written to disk. Modification times reported to the plugin are a bit imprecise, but if an image file seems to be less than a second old, it is not imported.
20091205.8 Minor internal debugging tweaks.
20091022.7 Added a first draft of some rudimentary support for Lightroom 3 Beta. See this important note about plugin support in Lightroom 3 Beta and Lightroom 3, including future plans for features and my registration system.

Enhanced the one-click upgrade stuff quite a bit, now detecting ahead of time when it will fail because the plugin is installed where Lightroom can't write (if Lightroom can't write to it, it can't update itself). I also added a progress bar, and now download in smaller chunks to avoid 'out of memory' errors on the larger plugins. Do remember that this new functionality becomes available after you upgrade to or past this version, when you then upgrade with it.

20090521.5 Fixed a "loadstring" error some users got.
20090511.4 Now it quietly ignores images that Lightroom can't process. The failure is noted in the plugin log. (It's on the to-do list to expose an "activity log" where this event might be more readily accessible.)
20090510.3 Added a link in the Plugin Manager to the plugin's update-log RSS feed.

Added a "show splash dialog" option to the "upon import of a new image..." configuration, so that you can be informed when the plugin imports a new image in the background for you. You can configure whether the splash is shown, and if so, for how long before it automatically disappears. I've not tested this too much, so I don't know what problems it might cause having a background task (the folder watch plugin) throw up a splash dialog. It seems to work okay, except...

.. if a splash dialog pops up while you're painting local corrections, it'll do bad things to the current brush stroke, such that after dismissing the splash dialog, you'll have to undo the brush stroke you were working on and redo it.

I also realized one other caution: when the plugin imports a photo for you, that import action is added to the undo stack. This happens whether the import is accompanied by a splash dialog, or if it's totally silent in the background. The worry this creates is that if the import happens just before you do a bunch of undos, you may unwittingly undo back past the import and not even notice. The only option I see around this problem is even worse: having the import pop up a warning dialog that it's about to clear the undo stack, and then actually have it clear the undo stack. So, if this is a practical worry for you, enable the splash screen.

I also fixed the home-page url, and the folder-to-watch edit box, which would sometimes show only a partial folder path on a OSX. The report of overall session imports is now red when something's been imported this session.

It also turns out that if you reload the plugin, Lightroom doesn't completely do away with the previous instance, so it was possible to have multiple versions of the plugin running and not even know it. It's a big hairy mess, but I think I've worked around it in this version. The plugin also refuses to scan if it's not enabled.

I also added an option to restart the watch when Lightroom is started, so that you can have it running all the time. Along with that is an option to throw up a splash screen during Launch if the plugin has been set to scan at launch. You can use this to remind yourself that the thing is running.


First public version. Pretty rough at this point. Currently, everything is controlled from the Plugin Manager, which is probably not the best UI. Pick your folder to watch, the frequency with which to check, then click the "watch!" checkbox to turn it on. You can then leave the Plugin Manager and, most likely, open the target folder in Grid Mode (perhaps sorting to most-recent first).

Some random notes:

  • The plugin infrastructure does not allow plugins to do anything with develop or metadata presets, so the imports are plain vanilla.
  • You almost certainly never want to point this at a slow disk, or if you do, have it check very infrequently. Lightroom can seem to lock up momentarily when attempting to access some disks.
  • In the Plugin Manager, while a folder is being watched, keep an eye on the time reported in the "Scan Status". It's okay if the first scan takes a while, but if subsequent scans take a long time, you'll want to scale back the check frequency. How long is "a long time" depends on your overall machine load and personal preferences.
  • Conversion to DNG not yet supported; I hope to add it soon.
  • A Lightroom plugin has only a limited ability to set image metadata, some of which I've incorporated (rating, label, and title). You may want to make use of a Smart Collection that keys off one of these. For example, have the plugin set the title of auto-imported images to "autoloaded", with a Smart Collection of all images with a title of "autoloaded". This way, you can change the title to something else once you've address a particular image. (It would make the most sense to use a special keyword for this, but Lightroom does not allow a plugin to set image keywords.). Note, though, that a Smart Collection can lag behind reality for a few seconds, so if you're interested in seeing the images ASAP, you'll want to leave the target folder open in Grid Mode.
  • The plugin does not yet ensure that an image file is complete before attempting to auto-import it. This means that images that are written slowly by less-than-smart applications may not be properly imported. (They won't be corrupted, just not imported properly the first time.) Please let me know if you run into problems along these lines.

The 30 most-recent comments (out of 181; see all), most recent last...

The pluging imports one and one photo, as opposed to the native autoimport that does all images it discovers in a folder in one batch. For large amounts of photos that increases the time it takes to import using the plugin quite much. Is this intentional? Is there any workaround on this?

The plugin will import as many files as fit the current criteria (age and newness, etc.). If it’s not working as you think, perhaps send a plugin log after a failure, being sure to include specifics on exactly which file wasn’t imported when. —Jeffrey

Can i use it with multiple catalogs? each with their own settings and “drop” folders?

If you make a preset of settings, you can tie that to load automatically when you load a specific catalog. —Jeffrey

Hello! I have to thank you for developing this plugin. It has allowed me to build a stable workflow at a live event I’ve been working for years.

In a nutshell, I shoot tethered RAW files with another application and use Folder Watch to import photos into Lightroom, apply a develop preset, and publish processed/watermarked jpegs to a shareable folder on my hard drive. This way, I can shoot RAW files all night while processed JPEG files get saved in close to real time.

Everything works great, but I have two minor issues. If I have a develop preset applied with the plugin, and then later in the develop panel change the settings for that develop preset (right-mouse-click on preset, “Update with Current Settings”), the preset then gets deselected in the Folder Watch plugin (Apply Develop Preset gets set to None). This is just a little annoying if I’m making quick adjustments during a job because after I change a Develop Preset, I then have to reopen the plugin settings to make sure it gets applied in the workflow. I only bring this up because there was one release awhile back that didn’t clear a preset if i altered it. If that’s something that can be looked at, I would appreciate it, but understand if it’s also a limitation of how Lightroom does business.

One other light issue i’ve noticed is that if I right mouse click on an image in a publish collection and hit “Mark as Up to Date” (so it won’t republish certain images after changes have been made), the plugin stops publishing all together, even if there is still a collection selected in “Publish This Collection”. Photos will import just fine, but I have to reload the plugin to restore it to full functionality any time i selectively mark certain photos as up to date.

Thank you! And I can’t overstate how helpful this plugin has been to my workflow.

The first issue seems to be a bug in Lightroom… I’ve submitted a bug report, and made a workaround in the version of the plugin that I just published. I can’t reproduce the second issue… please send a log just after encountering it. Thanks. —Jeffrey

Hi Jeffrey

I hope you’re doing well.

Me and my colleague have been testing a few options for lightroom plugins to convert, run a basic preset and then export as jpeg. Your one looks exactly like what we’ve been looking for!

We’ve been testing but we’ve got one issue that we expect will be a simple fix.

We tried to use a basic preset with the plugin which converts the image to black and white and then publish via a publish service, we manage to get the basic flow running where plugin picks up images from the watched folder and then sends them to the folder defined int he publish service, but the preset doesn’t get applied at all, only the settings from publish service gets applied, we tried all the possible settings but still no luck.

Could you direct us in where we’re going wrong?

I take it you’re using the “Apply Develop Preset” option (third under “Upon Import of a New Image”), and it’s not working? Does it work when you apply the same preset manually? If so, please send a plugin log and I’ll take a look. —Jeffrey

Hi Jeffrey,

Thanks for a great plugin.
Have had an issue, with FW placing new folders outside of the main images folder.
Which I then have to manually reimport.
Was on v 8..140
Just updated to latest.

Any thoughts on this?


The plugin doesn’t move images unless you’ve asked it to move images, and even then moves them only where you tell it to move them, so I’m not sure what exactly you’re reporting. Perhaps send a plugin log, citing specific examples. —Jeffrey

Hi Jeffrey,

This plugin has been working well for years now, but I’m having an issue. Years ago I suggested the “silently ignore errors” option which you implemented (thank you!). However, while this option works, I recently noticed that when an error occurs (particularly a file moving error), the plugin stops scanning and the “enable scan” option becomes unchecked. As a result, I have to go into the plugin manager to enable scanning again (and then it starts without issues). Would it be possible for the plugin to simply always continue scanning rather than stopping?

This issue happens when a file is not finished writing from a camera wifi SD card to the location that folder watch is monitoring (because sometimes the wifi signal is lost). Folder watch tries to move the file but can’t at that moment so an “unknown error” occurs and folder watch stops scanning. I have tried using longer times for “file unmodified for” but that still doesn’t work well because the SD card could be offline for an extended period of time. Eventually that same file finishes writing and after I re-enable scanning, folder watch moves the file and imports into lightroom without issues.

Would it be possible to make it so that the plugin continues to scan (by simply moving to the next file or just waiting for the next scan) rather than just completely stopping?

Any reply will be appreciated. Thank you.

I’m a bit worried about unintended consequences, but I’ve updated the plugin to honor the “ignore…” option even for file-move errors. We’ll see how it goes… —Jeffrey

Hi Jeffrey

I do like your plug-in very much.

There’s one thing I could not accomplish: I want to import only images files. Means: *.jpg, *.nef, *.dng, *.arw (all of them)

In the settings I found: Filenames to consider — Lets you include or exclude filenames that match a filename pattern like “*.jpg”.

This works as long as I only choose one type like *.jpg
I want to put in a list like: *.jpg *.nef,*.dng,*.arw
For me this doesn’t work. I tried several separaters like commas, pipe, hyphens…
Should it work?

Cheers, Werner

Yes, it should work….. if you upgrade to the new version of the plugin that I just released 😉 —Jeffrey

Hi Jeffrey,
thank you this plugin seems what I need to import whole sessions into LR.
Unfortunately, my incoming folder contains sub folders per sessions (client, name and location) and I don’t see how to add each session to a different collection, there is one ‘Add to standard collection’ but only existing and not using Template Tokens. What I would need is to add in a collection located in an existing collection set root then specify a sub collection set and collection path with text and tokens (like FolderName).
Master photo is in folder: {watch root}/client/20190831 Big Party
Add to collection is set as: (existing collection set) Import sessions (collection path): {FolderName=0}/{FolderName=1}
then photo lands in collection: Import sessions/client/20190831 Big Party

Would it be possible? It would save a lot of time in batch. Thank you for any feedback

Right now I move 1 session folder at a time in the watch folder, copy the name of the source folder, wait for the plugin to finish the job, go to an “Import unsorted session” collection, select all, create a collection with pasting the name in “Import sessions/client” collection set with “add selection to this collection” checked (having eventually created the client collection set while waiting)… 🙁

Lionel (France)

It’s not possible at the moment, sorry, but I’ll add it to the todo list. —Jeffrey

Hi Jeffrey

I’m from Switzerland and much appreciating your LR plugins!
When I updated to the latest folder-watch-plugin (20190831.142) nothing worked anymore.
I couldn’t even open the plugin manager.

?:0: attempt to perform arithmetic on a boolean value

When I deleted the plugin file and restored it to the older version everything worked again.
I hope this can help you to find the bug.

Thank you so much for developing these awesome plugins!


It sounds as if your unzip of the download got corrupted. I don’t hear about it often, but some browsers that auto-unzip seem to introduce some problems. Perhaps try downloading with a different browser? —Jeffrey

Folder Watch

it is normal that when I start LR it will take more than 30 minutes to scan about 90000 pictures until it a new folder will be added?


I suppose it depends on the nature of the device being scanned, but Folder Watch is not intended for this kind of situation. It’s intended to watch a normally-empty folder for new files being dropped by some external application, and bringing them into Lightroom. It’s certainly not intended to watch all the folders that are already registered within Lightroom. —Jeffrey

Experiencing same issue with folder-watch as Damian (?:0: attempt to perform arithmetic on a boolean value) even after using different browser to download and manually unzip. Rolling back plugin is fine. Works by rolling back. LR 8.4.1.

Hi Jeffrey,

I experience the same issue with folder watch as Damian and Don. Version 141 is the last version that works here.
I tried to download with Safari and Firefox on my Mac but same issue.
After the update, I don’t have the button to send the plugin log…

Best regards,


I don’t know what to tell you… I’m not getting reports of problems. I’m sure the zip file on my server is fine. Could it be some kind of security thing on your system diddling the download? I’m really at a loss to understand why it wouldn’t work. —Jeffrey

Hi Jeff!
I have a problem with the plugin. I used the plugin for a photo both, every time I took a picture by tethered shooting, it automatically sent it to the publishing folder – exports the image and from there a printer automatically prints it. But occaionally it occured that a previously published picture was sent to the publish folder as well and appeared for just a second in the output folder. The printer printes then the old picture as well. Another problem was, that even when the box “new images only” was checked, old ones were sent to the publishing folder!
So I tried to update to the latest version of folderwatch (in the plugins manager), but this crashed lightroom. And that’s now the actual major problem, I cannot even access the LR plug-ins manager anymore, I receive the error messagefor internal error: “?:0: attempt to perform arithmetic on a boolean value” So I really don’t know what to do, I updated and reinstalled LR already with no effect. Any ideas?

Oops, I replied to your later message about .141 before having seen this message, sorry. If you can send the plugin log, I’d appreciate it. First delete/move the plugin so that Lightroom won’t be able to load it, then if you use any of my other plugins to view that plugin’s log (via a button in the upper-right of the plugin manager), you’ll see where the logs are, and in that folder should find the folder-watch-log.txt file left over from before. Could you mail that to me ( You can get .141 here, but I’m not sure whether it will run in Lr9. —Jeffrey

Hello Dan and Damian!
Seems I have the same problem like you! How did you remove the script? I have no access to the plugin-manager therefore I cannot install or uninstall this or any other scripts…! Also reinstall LR didn’t help. Any suggestions, is there a way to remove scripts manually?

Do you already have a solution for the “?:0: attempt to perform arithmetic on a boolean value” error message? I saw there are more users with the same error.
I upgraded in the meanwhile to LR9 and now I cannot use the old versions anymore (not compatible with LR9) and the new version gives the errore message.

Earlier versions don’t work, same as current version. Only solution for me is using an older LR version (2015 I think). Sad, was a great little tool!

It’s fixed now. Sorry for the hassles. It was difficult to track down because it worked fine for the vast majority of people, but now having discovered what was wrong, I don’t understand how it worked for anyone. Sometimes the bowels of Lightroom are a true mystery…. —Jeffrey

Just a quick note: there is the option to restart scanning automatically after starting up LR. However, when I close and reopen LR, the option “Add to Publish collection:” resets to ‘none’. Which results in no auto publishing (to a folder on my drive).
Can you help me out?
I can’t reproduce this on my side; could you send a plugin log after encountering the reset to ‘none’? —Jeffrey

Recently I keep getting an error message saying “LrPhoto:setPreset: must be called from within a withWriteAccessDo block”. It appears every 10-20 images. Any advise on how to correct this issue?

This is, unfortunately, something that a plugin has little control over. It’s fairly ridiculous, but the way Adobe built the plugin infrastructure makes it impossible for a plugin to know that it has permission to access the database. It can be “fairly certain” and therefore give it a try, but depending on the timing of other things within Lightroom and on your computer, you might get unlucky timing and in the end don’t have permission. That’s what you’re running into here, I think. It’s pretty rare that it doesn’t work (I can’t get it to not work, so it’s difficult for me to program around it), but maybe something about your catalog has fallen into some kind of trap, such that it’s happening more? It’s all just frustrating conjecture. We can only hope that it eventually goes away…. —Jeffrey

Do you know where the error is?

Thank you very much in advance for your reply


Folder Watch should work with every version of Lightroom Classic since Lr4. If it’s not working for you, and you know you have the most-recent version of the plugin, then perhaps try downloading with a different browser. For some reason, some browsers seem to corrupt some downloads…. —Jeffrey

Thanks Jeffrey for that plugin – very useful! The only thing that is really missing, is DNG-Konversion upon import. Any chance of seeing that soon?

No, sorry, Lightroom doesn’t allow for it. —Jeffrey

Hi Jeff!

I don’t know if my comment was committed correctly. I just wanted to ask if there is a way to access LrTasks and LrApplication from a custom script that I run for each photo?

PS: I want to create virtual copies of each photo, process them and add them to the collection to be published.

No, there’s currently no way to do that. I suppose I could add a Lua hook, though. Let me give it some thought…. —Jeffrey

I have a folder with 25,000 subfolders. I had it set to monitor the parent folder as new subfolders are added often. When running the plugin it imeditalty goes into ‘not responding’. But looking at the library catalog on my computer, the file is growing in size, and write time is increasing.

I’m wondering why the software would run, but show as not responding? I have a Ryzen 3600 Cpu, and 32GB ram. Maybe have the option to increase some resources for computers that can handle the extra RAM or CPU usage?

Let me say up front that the plugin was not designed to watch 25,000 subfolders. Or even 25, really. Because of limits within Lightroom, it can’t access hooks in the operating system that would make watching that many subfolders feasable, so it has to do a blunt walk of all folders looking for something new. Each time. From scratch. I suspect the “not responding” is within Lightroom when the plugin asks it for a list of all folders. Lightroom probably wasn’t expecting to be asked in that situation either. —Jeffrey
