Is there some kind of file management app that can locate files that are the same except for their names? For instance, I've had occasions where I have imported photos from an iphone, then exported them from photos and renamed them. But afterwards I realize I may have saved the photos with their original default exported names on an external drive, and don't need them any more. But matching them with their renamed counterparts to ensure that I don't need them any more ends up being a time consuming chore. I would love to have an app that finds all the duplicates for me when I get sloppy and don't keep track of things the way I should.
