As a result of using the Duplicate Photos Fixer program on my Mac, I now have quite a few photos marked in Lightroom as "could not be used because the original file could not be found", and a small ! mark appears on the thumbnail.
I would like to know if I can select all such photos (over 400 across my collection of about 20,000) by some filter? I have not figured this out, and it would be useful to track them down (to then set as Rejected and then removed from the LR catalogue) without having to wade through hundreds of folders etc.
Any suggestions for a filter would be much appreciated.
PS I probably shouldn't have trashed the pics from Duplicate Photos Fixer but that's now water under the brifge....
Use the menu command Library->Find All Missing Photos
To fix the exclamation point icon, please read these instructions: Adobe Lightroom - Find moved or missing files and folders
