Summary
dupeGuru is a free desktop tool for locating duplicate files on Windows, macOS, and Linux. Its Standard, Music, and Picture modes provide different scan settings. Filename scans can find similar names, while Music mode compares filenames or selected music tags. Picture mode looks for similar images, and can compare different dimensions when that preference is enabled. Contents scans identify exact matches, using file size to rule out impossible matches before comparing contents; recursive scans can also find duplicate folders. After a scan, users can filter and sort results, compare a file with its reference in a details panel, and delete, move, or copy marked items. Reference folders and duplicate groups are designed to protect reference files and retain at least one item in a group. The documentation recommends checking results before deletion, since similar-word matching can produce false positives. Picture matching compares every image against every other image, which can make scans slow and CPU-intensive. The project is GPL-3.0 licensed.
Who it is for
dupeGuru suits people who want to find and review duplicate files across folders on a Windows, macOS, or Linux computer. Its separate music and picture scans are useful for collections where names or contents alone may not identify similar items.
What is good
- Offers Standard, Music, and Picture scan modes.
- Finds exact content matches and similar filenames.
- Can identify duplicate folders in recursive content scans.
- Allows filtering, sorting, and file comparison before action.
- Available for Windows, macOS, and Linux.
What to know first
- Picture matching may be slow and CPU-intensive.
- Similar-word matching can create false positives.
- Review is recommended before deleting marked duplicates.
Verdict
dupeGuru provides several matching approaches and review tools before file actions. Picture scans can become resource-intensive, so users with large image collections should account for that limitation.
