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.

Functional & Fashionable

Nifty little app that delievers what was promised. I was quite impressed by the efficiency of the scans, and the auto select feature which saved me a great deal of time. Also, the interface was sleek, and inviting which surprised me for this type of system cleaning app. Would I upgrade to Pro? Probably if I had a great deal of files to go through!

It’s great!

I’m impressed by this app. It shows types of duplicate files and proposes useful cleanup hints. Great interface and ability to skip folders from seraching list.
Actually I thought that a have just a couple of duplicates, however, the app found 100+ duplicate files.
The search speed is awesome!
