dupeGuru is a free, open-source, cross-platform duplicate file finder for Windows, macOS, and Linux that detects duplicates by analyzing file content in addition to filenames using a fuzzy matching algorithm. It runs on Python 3 with a UI built for macOS (Objective-C/Cocoa) and Qt5 on Windows and Linux, offering fast scans, customizable rules, and grouped results to review duplicates. It enables safe management actions—delete, move, or copy duplicates—while protecting important files with a Reference Directory and highlighting the best version with a Power Marker.
