Download dupeGuru – Free Duplicate File Finder for Windows, Mac, and Linux

dupeGuru is a free, open-source duplicate file finder for Windows, macOS, and Linux. It quickly scans your folders for duplicate files and helps you decide which copies to delete, freeing up valuable disk space. It goes beyond simple byte-for-byte comparison, using fuzzy matching algorithms to find files that are similar but not identical — particularly powerful for music and photo collections.

dupeGuru comes in three scanning modes: Standard (for any file type by content hash), Music (matches audio files by metadata tags like artist and album), and Picture (detects visually similar images even if they differ in resolution, format, or minor edits). Each mode is tuned for its specific type of content, giving you smarter, more relevant results.

The results view lets you review all matches, mark files for deletion, and apply filters before committing any changes. Files can be moved to a custom folder or sent to the Recycle Bin, making the process reversible and safe.
