Almost Perfect

It's a very good app. I wanted to clear down my Music folder. On the first run it picked alot of duplicate items up, on the second run I had expected it to say no duplicate items, but it was still discovering duplicate items (same folder). Eventually I got the message stating no duplicate items found. I would have given this 5-stars, had I not have to run it more than twice. I would recommend this app though, it's quick and the best one I've come across.

Such a good app

I've had Duplicate File Finder Pro for quite a while now and it is excellent.

It is extremely well designed and a pleasure to use. It has been faultless for me.

I wish there were more apps like this one where the developer has clearly taken great care to make something good.
