dupeGuru is a tool to find duplicate files on your computer. It has three modes, Standard, Music and Picture, with each mode having its own scan types and little features.

Although dupeGuru can easily be used without documentation, reading this file will help you to master it. If you are looking for guidance for your first duplicate scan, you can take a look at the Quick Start section.

It is a good idea to keep dupeGuru updated. You can download the latest version on its homepage.
