I am running OSX 10.12.6 and sorting a large number of mostly not native digital pictures (scans from negatives). Using the command:

fdupes -r -A  "/Users/yves/Pictures/Photothèque.photoslibrary/Masters" 

I get many results of duplicates like below, same files but in different subfolders:

  1. Is this normal behavior ? I understand the same files may have been imported several times, but I wonder:

  2. is is safe to eliminate the duplicates and how best to do it ? For convenience I am using exiftool in combination with Applescript to adjust (reconstruct mostly) picture metadata in the Photos library from selected pictures and want to make sure I do this only once and for the correct file.


If they don't come up in Photos.app, I wouldn't touch what goes inside .photolibrary package. There are just too many questions of Photo library going wild. You anyway won't be saving much space there, if the files are tiny.

    TIFFs usually aren't tiny :-) But I agree, removing duplicates directly within the package isn't a good idea. – nohillside Feb 23 '20 at 14:29
