Dedupo helps you find and delete duplicates. You can set the criteria of duplicates, whether it's the same size,content,name and/or modified date. Dedupo uses byte to byte comparison to find duplicate content so the duplicates have 100% exact content.


The Auto Mark feature on Dedupo is very handy and will save you a lot of time. You can automatically mark files by comparing date modified, name length or folder.

Requirements:
OS X 10.6-10.8
