dupeGuru

Purpose: dupeGuru is a desktop GUI tool for finding duplicate files on a computer.
Scan modes: It has Standard, Music, and Picture modes, each with specialized preferences and scan types.
Filename matching: Filename scans can use fuzzy matching to find similar names that are not exactly the same.
Music scans: Music mode can compare music tags and display music-specific information in duplicate results.
Picture scans: Picture mode can scan for similar pictures that are not exactly the same.
Content scans: Contents scans consider files duplicates when their contents match exactly, using file sizes to narrow comparisons and MD5 hashes to compare contents.
Result actions: Users can delete, move, or copy marked duplicates, and can filter and sort results.
Deletion safeguards: The reference folder and duplicate group systems are designed to prevent deleting protected reference files and to retain at least one member of a duplicate group.
False positive review: The documentation recommends reviewing duplicates before deleting them and provides a details panel to compare a file with its reference.
Platforms: The homepage lists Windows x64 and x32, Ubuntu x32 and x64, and macOS 10.12+ downloads.
Languages: The homepage lists English, French, German, Chinese (Simplified), Czech, Italian, Armenian, Russian, Ukrainian, Brazilian, and Vietnamese as supported languages.
Support: The maker directs users to GitHub to report bugs or suggest features by opening an issue.
Performance limit: Picture matching compares every picture with every other picture, making the comparison count quadratic in the number of pictures.
License: The GitHub repository identifies the project as GPL-3.0 licensed.
Price from: Free
