dupeGuru review
A free, media-aware desktop finder with exact and fuzzy matching across three platforms.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
dupeGuru is a free, open-source desktop application for finding duplicate files on Windows, macOS and Linux. It suits users who want to inspect and manage duplicates on local computers, especially when filename matching alone is not enough. Standard, Music and Picture modes address general files, music libraries and images, while grouped results present duplicates alongside reference files for review.
Its strongest distinction is the range of matching methods in a small desktop workflow. Standard mode can compare exact file contents using hashes and find similar filenames with fuzzy matching. Music mode compares music tags, while Picture mode uses fuzzy picture comparison. Users can inspect file details, open files in their associated applications, filter and sort results, and apply regular-expression filters. Folder states—Normal, Reference and Excluded—give users control over how selected locations are treated during a scan.
The trade-off is scope rather than matching depth. dupeGuru is designed around user-selected folders, so it is a better fit for targeted cleanup on desktop storage than for a broader service spanning other locations. After review, marked files can be sent to the system Trash or moved and copied elsewhere. The source is available under the GNU GPLv3 license, and downloads cover the three supported desktop platforms. Choose dupeGuru if free, open-source software and media-aware matching matter most; choose an alternative if you need AI-assisted detection or a scanning model that extends beyond selected folders.
