DFF has been wonderful in helping me to remove duplicate files after migrating three portable hard drives onto one large disk. It saved me 415GB of file space out of the original 1.9GB.App Store

Duplicate File Finder lets you get more free disk space by removing unnecessary identical or similar files and folders from your Mac. It works with a variety of file formats and has a really fast scanning algorithm to find matches.Fixthephoto

The app takes only a few minutes to fully scan my computer. It makes it easy to delete cache files and to dump the trash, which once saved me almost 2 GB when I forgot to do it. Simple, Quick, and Easy. Love it.App Store
