Duplicate File Finder
By iBoostUp Pty Ltd
Open the Mac App Store to buy and download apps.
Duplicate File Finder helps you regain disk space and reduce clutter by searching for files with identical content, irrespective of location or filename. Duplicate File Finder gives you the opportunity to review and select individual files for removal, but rest assured that in case of inadvertent deletion your files are recoverable from Mac OS's Trash until emptied.
A mistake to download
Thought I'd be able to delete a few hundred duplicate photo and music files easliy with this app. Waste of money though. Not sure how any developer would charge 3 bucks for this when over 2/3 of the reviews are terrible. It returned zero relevant results and did nothing for me. It crashed the first 5 time I tried to run it. Not trying to be a jerk here, but if you want to sell a good product, develop a good product first, test it, and then release it. Cute icons aren't worth my 3 bucks.
Tried about 5 scans with only one being successful. The others were crashes. 4 out of 5 times I get a Duplicate File Finder quit unexpectedly notice. The one time it did run a scan successfully it did actually identify duplicate files. Kind of defeats the purpose if it will not run on large folders.
Moved all music files to one place. ran the program 4 times. deleted 4000 dup songs. deleted all songs out of iTunes, and re added them with. itunes is showing 1395 dupes still. really not a great program. Waste of 3 bucks. deleting dupes by hand anyway now.
