dupeGuru review (2026): is it any good?
Free open-source tool that finds duplicate files by name or content
dupeGuru report card
Very good · out of 4.0 · graded Nov 13, 2026
Best for finding duplicate files for free
dupeGuru finds duplicate files by name or content, with separate music and picture modes, and it's free under GPL-3.0. But the site looks unmaintained, with a 2018 copyright line, and low-threshold fuzzy scans return false matches you have to review by hand.
Who dupeGuru is for
- Fits if you want a free duplicate finder on Mac, Windows or Linux
- Works for sorting duplicate music and pictures
Who dupeGuru is not for
- Skip it if you want an actively updated site: the copyright line reads 2018 and recent downloads are on GitHub
- Not for you if you have an Apple silicon Mac and want a native build, as none is listed
- Watch out: fuzzy scans at a low threshold return false duplicates you must check yourself
- Watch out: the site's own text disagrees about which platforms it runs on
Why dupeGuru gets a 3.0

Keep dupeGuru, or make your own?
Keep it
dupeGuru is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 3.0 is higher than 154 of the 186 other desktop utilities we grade.
What you could not
- A file manager working directly on your disk.
- Deleting system files without breaking anything.
- Apps for macOS, Windows and Linux that stay in step with each other.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. dupeGuru’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is dupeGuru?
dupeGuru is a cross-platform desktop tool for finding duplicate files. It can compare filenames, with fuzzy matching, or file contents, and has separate Music and Picture modes for tags and similar images. Found duplicates can be deleted, moved or copied. Its source is published on GitHub under the GPL-3.0 license.
Worth knowing
- The vendor's site is sparse and its copyright line reads 2018; recent downloads are on GitHub releases.
- The Mac download is listed for macOS 10.12 or later, and the page lists no ARM-specific build.
- Fuzzy scans at a low threshold can return false duplicates that you have to review by hand.
- The site's own text is inconsistent about platforms: one paragraph also says it runs only on Mac OS X and Linux.
Key features
- Filename and content scans
- Scans either filenames or file contents. The filename scan uses fuzzy matching, so similar names are found as well as identical ones.
- Music mode
- Scans music tags and shows music-specific information in the duplicate results window.
- Picture mode
- Scans pictures fuzzily to find images that are similar but not exactly the same.
- Safety features
- A reference directory system and grouping system are meant to stop you deleting files you did not mean to.
- Delete, move or copy
- Duplicates can be deleted, moved or copied elsewhere, and results can be filtered and sorted to weed out false matches.
