dupeGuru

dupeGuru is a graphical utility that scans a computer for duplicate files. It can compare files by name, content, or, for specific media types, using a fuzzy‑matching algorithm that detects similar filenames and, in Music and Picture modes, compares tags or visual similarity. The core scanning engine is written in Python 3 and is shared across platforms, while the user interface uses Objective‑C and Cocoa on macOS and Qt5 on Linux and Windows.

The tool is aimed at users who need to locate and manage redundant files, such as personal computer owners, media collectors, or anyone looking to free storage space. Its customizable matching settings let users adjust sensitivity, and the results can be filtered, sorted, and acted upon by deleting, moving, or copying selected items. Safety features, including reference directories and grouping, help prevent accidental removal of unintended files.

Supported languages cover a wide range, including English, French, German, Chinese (Simplified), Czech, Italian, Armenian, Russian, Ukrainian, Brazilian Portuguese, and Vietnamese. The application is stable and available for macOS, Linux, and Windows.
