Excellent - I’ve been workingon this project literally for years - collecting files off of old hard drives, CD’s, memory sticks and phones… I finally have them now, and NOW WHAT? Well, I thought, the first thing is to remove all the duplicates? And how am I going to do that? This app is a godsend. Excellent job. Oh, and the best thing is being able to try it out before paying. Any app that wants me to pay first, I don’t even bother.

Fast and easy in use - It works perfectly and surprizingly fast - just a few seconds for scanning folders. And it has an extremely easy to use and nice interface. I've tried many apps and gave up them over time due to being untrustworthy. But this one is EXACTLY what I was waiting for - 100% accurate.

Review by K-4-A-D

My gosh this app is great, blows away the competition! - This app is incredibly incredibly fast…I ran it against several other well-reviewed competitors and it just blew them out of the water, scanning two terabytes of photos, files and movies, it found everything in seconds while the best of the other lot was still working on it after several minutes. Pretty remarkable actually. Also, it’s sorting capabilities for reviewing duplicates is next to none. Great user interface, clear concise and thorough, leaving mystery out of the equation. The developer’s “Menu Cleaner X” is superb also.

Review by shutyourpiehole

Good App but the nagging is tiresome! - I have quite a few pieces of software to find duplicates. Some work, some don’t, especially with Photos and an external drive with a complicated hierarchy of folders. Duplicate File Finder seems to be working nicely but I barely launched it before it began nagging me to buy MORE of their software. I PAID for this software and I can’t use it without suffering through commercials? That is enough to make me delete the software but I’m hoping this will stop the nagging. I can’t comfortably recommend this software without being give time to use it but based on one scan of my home folder, it worked quickly and found many files to delete..

Review by AR Frost

Insanely Great!!! - I have waited sooo long for this app! I just deleted 9 GBs of duplicate files (don’t judge! Long story…) in about ten minutes. I’m definitely paying for the upgrade so I can mop up all the duplicate and ‘similar’ folders.

Found my duplicates really fast - All I have to do is select a folder and click auto-select and the duplicates will be gone.
