dupeGuru is a free, cross-platform (Linux, OS X, Windows) GUI tool to find duplicate files on Linux, OS X, and Windows PC.
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. It has a special Music mode that can scan tags and shows music-specific information in the duplicate results window. It also has a special Picture mode that can scan pictures fuzzily, allowing you to find pictures that are similar, but not exactly the same. You can tweak its matching engine to find exactly the kind of duplicates you want to find. Do whatever you want with your duplicates. Not only can you delete duplicates files dupeGuru finds, but you can also move or copy them elsewhere. There are also multiple ways to filter and sort your results to easily weed out false duplicates (for low threshold scans).
Supported languages: English, French, German, Chinese (Simplified), Czech, Italian, Armenian, Russian, Ukrainian, Brazilian, Vietnamese.
