"Very good program to find duplicate files"

Reviewer: -AllDup Fan

Review Date: 2016-04-08

Pros: I've tried many others programs for finding duplicates. This is the fastest program to compare files exactly byte for byte. It had also a option for a file preview. Very useful for pictures.

Cons: none

Other Thoughts: none
