This app is easy to use and helped me so much! I’m personally not the best at keeping my files organized, but this saved my bacon! I really like the fact that you can scan multiple folders against each other. Fantastic!Rfroberts

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.Alex Calgony

I’ve been using the app for a few days to try out and it works outstandingly well. For finding duplicates but also for merging folders. The interface is great, and it’s great to go through your files and select which ones you want to keep and which to delete.T.0011
