Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
3.0
GPA, above 154 of the 186 other desktop utilities we grade
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.
To get you started, here are 8 things to know about dupeGuru, taken from its own pages and our grades.
Scan modes and a fuzzy threshold to tune, and results to review by hand.
- 1
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.
- 2
It is free

- 3
It runs on 3 platforms
macOS, Windows and Linux.
- 4
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.
- 5
Music mode
Scans music tags and shows music-specific information in the duplicate results window.
- 6
Picture mode
Scans pictures fuzzily to find images that are similar but not exactly the same.
- 7
A 3.0 GPA, above 154 of 186
That is against the other desktop utilities we grade, on value, the free plan, features, ease of use and platforms.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | Free under GPL-3.0, with no paid edition. |
| Free plan and trial | A | The whole program is free to download on every platform listed. |
| Features | B | Filename and content scans, music and picture modes, and delete, move or copy. Nothing in the listing is missing from the job. |
| Ease of use | C | Scan modes and a fuzzy threshold to tune, and results to review by hand. No store rating is on record. |
| Platforms and integrations | C | Mac, Windows and Linux, computers only. No phone or web version, and no ARM Mac build is listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- People who want a free duplicate finder on Mac, Windows or Linux
- Photo and music collections with near-duplicate files
- Users who want to inspect or build the source
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.

Where it stands
Its grades against its category, and whether to keep it or make your own

What paid plans start at, a month (each step along is roughly double) →
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
