dupeGuru is a tool to find duplicate files on your computer. It can scan either filenames or contents. The filename scan features a fuzzy matching algorithm that can find duplicate filenames even when they are not exactly the same.

Good with music. It has a special Music mode that can scan tags and shows music-specific information in the duplicate results window.

Good with pictures. It has a special Picture mode that can scan pictures fuzzily, allowing you to find pictures that are similar, but not exactly the same.

Customizable. You can tweak its matching engine to find exactly the kind of duplicates you want to find. The Preference page of the help file lists all the scanning engine settings you can change.

Safe. Its engine has been especially designed with safety in mind. Its reference directory system as well as its grouping system prevent you from deleting files you didn’t mean to delete.
