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.

I love this app! My computer had become a mish-mosh of years of repeated backups (thus duplications) and nested folders within layers of nested folders. This app has helped me identiy duplicate photos, folders and choose which to retain.
