How to run Find similar files
Why a limit of 5000
Can I change this limit

Q: How to run Find similar files
A: Running the plug-in require only 2 steps:
  1. Select the images in Lightroom you want the plug-in to work on
  2. Choose Menu -> Library -> Plug-in Extra -> Find Similar File names
    Choose "Find similar file names"

The result of the search for images is stored in 3 Collections in Lightroom, see screenshot below

  1. Source files
    This collections holds all images you selected as input for the search operation.
  2. All_files_found
    This collections stores all the images found, inclusive the selected images.
  3. Different_from_Source
    The difference between the 2 collections = all images found exclusive the selected ones themselves.

Q: Why a limit of 5000
: The search mechanism this plug-in uses is similar to that of "Smart Collections". To protect the user from very long running tasks, this limit is set.
However, this limit can be changed easily.

Q: Can I change this limit
: Yes you can, but at your own risk!!

Follow these steps to change the maximum number of photos to be checked:

  1. Close Lightroom
  2. Go to the "Find similar files" plug-in directory
  3. Search for files called like "TranslatedStrings_xx.txt"
    xx stands for the language you are using.
    If your language is not there the default "en" will be used.
  4. Make a copy of the original file
  5. Open this file with an editor
  6. Search for the text "$$$/SimilarFileNames/Settings/MaxPhotos=5000"
  7. Change the number behind.
  8. Save the file
  9. Restart Lightroom
