Fast, Elegant Design and Worth the Upgrade - 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 removed thousands of duplicates within less than a day after years of copying files from one drive to another to create redundant copies. The duplicate folders and similar folders features are well worth the upgrade to remove multiple copies of directories at once, instead of removing each file seperately. This saved me a great deal of time as I had multiple copies of photo directories. The interface is fast and elegant. DFF took about an hour or two to analyze hundreds of thousands of files (1.9GB). It neatly organized them so one could remove duplicate folders, remove duplicate files in similar folders, and leave the unique files behind. All other files can be removed one at a time, and “Auto-Select” saves time clicking on which version you would like to remove. The application also safeguards you from removing all copies of a single file or directory by forcing you to enable that function and warns you politely before marking all copies for removal, if you chose to do so manually. Thank you for this wonderful application!

Doesn’t work - Tried it on a couple folders that had 20 duplicate files…it only found 1 duplicate. It will even tell me it finds more dupes but wont list them to remove them. Then you rerun it and (No duplicates found)

Review by DFFLuvr

Solution to my organization problems! - I had years of pictures (thousands) and many videos spread across 10-15 different thumb and external hard drives. How the heck am I going to organize!! Well, this software did the trick. I bought the Pro version. I combined most everything onto a 4 TB drive, ran a scan, eliminated duplicates, and now that I had more room on the 4 TB drive I loaded some more from the remaning hard drives and did anther scan. Now I have almost everything on one 4 TB drive with a backup copy of course. Now I’m looking for a solution to tagging and categorizing the material. DFF Pro is excellent!

This is the Duplicate Finder Software that you want! - I really like the speed and that I can easily select a folder after I see where the duplicates are. I especially like that I can "Favorite" a folder and it will automatically select all of the other duplicates. That is a very nice feature that I have not ever seen elsewhere (Windows OS included). And the vender was quick to respond to my question(s).

Review by nycmusicgirl

Would pay 10x as much for this app! - This is an easy interface, seamless, lots of options way to clean up files across multiple devices and systems and I only wish I had downloaded this app sooner. I love the flexibility of being able to remove duplicates based on file location, merging folders that are similar, and having it scan for specific file types. Cannot say enough good things about this software. A must for anyone with lots of files and backup systems.
