I notced my wife had a lot of duplicate files in her download folder and i have a few in my documents folder so grabbed this so scan and purge. it works fast enough although it did quite once when using on a documnets folder. I am running Yosemite so that could be why but not a big deal.

I've cleaned my macbook's hard drive using this app and I can say that it can certainly get the job done. The scanning speed is impressive. It scanned a 500 GB drive in 8 minutes. Would have loved a file preview especially for my duplicate photos but except this I really liked the app.

A decent app that does exactly what it says it will do. It finds everything you knew was there and everything you didn’t know. If you have duplicate files like I always seem to have, this app is the answer to your problems.

I had 500 Gb of music on an external hdd of which 70 Gb were duplicates. The app works well, it does exactly what it advertises. There are some minor glitches but they do not interfere with your workflow.
