# dupeGuru review (2026): is it any good? > Free open-source tool that finds duplicate files by name or content Checked Nov 13, 2026 ยท graded Nov 13, 2026 by ToolGPA. 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. - **Category:** Desktop Utilities - **Made by:** dupeGuru open-source project - **Website:** https://dupeguru.voltaicideas.net/ - **Runs on:** macOS, Windows, Linux - **Who should skip it:** Skip it if you want an actively updated site: the copyright line reads 2018 and recent downloads are on GitHub. - **Facts last checked:** Nov 13, 2026 ## Pricing As of Nov 13, 2026, dupeGuru is free to use. - **Pricing model:** Free - **Free plan:** The vendor's site lists downloads for each platform and no price or paid edition; the source is under GPL-3.0. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | dupeGuru | $0 | Free download for Windows, macOS and Ubuntu, with source code on GitHub. | Read from https://dupeguru.voltaicideas.net/ on Nov 13, 2026. Prices change, so confirm with dupeGuru before buying. ## 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. ## 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. ## ToolGPA grades **GPA: 3.0 out of 4**, graded Nov 13, 2026. 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. - **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. These are ToolGPA's own grades.
