Duplicate files got you down?

Lightweight, fast, and easy to use. I didn’t realize how many duplicate files I had until I bought this app. Thanks!

This app looks and acts humble, yet is powerful and delivers what it promises. It found duplicate files in my iTunes library and images accurately.

A friend recommended I clean my computer up with this, and now all the teachers at my school use it. Works great to clean up the worksheets, photos and videos we share.
