Best duplicate finder


I’ve used a bunch of these, and this one is definitely the best.

Pros: Finds duplicate folders, which is amazing. It’ll even find folders that are almost duplicates and show the differences between them. This feature is worth its weight in gold.

Cons: Would be nice to have a progress bar when scanning, and would be fun to have it say how many total gigs it’s found so far. That’s basically it.

Best of breed so far


I’ve tried at least half a dozen duplicate finders, and this is the best I’ve used so far. The interface is clean, clear and transparent. The results look reliable. In particular, the “similar folders” feature is quite nice.

This app was unbelievably ineffective.

In 12 seconds it went through my entire file and said there were no duplicates. I repeated the procedure THREE TIMES. Out of desperation and disgust , I bought Tunes mechanic which IMMEDIATELy fount 2000 duplicates which it is removing as I write this. Please don’t waste your money.
