dupeGuru vs Duplicate Files Fixer

dupeGuru is a desktop tool for finding duplicate files on Linux, macOS, and Windows. Its Standard, Music, and Picture modes offer different ways to compare files. Filename scans can detect similar names, while Music mode can compare names or selected tags and show music-specific details. Picture mode looks for similar images, including different-sized images when that preference is enabled. Contents scans identify exact matches, first using file sizes to rule out files that cannot match and then comparing contents with MD5 hashes. A recursive contents scan can also locate duplicate folders. Users can filter and sort results, preview files, and delete, move, or copy marked duplicates. Reference folders and duplicate groups are designed to protect reference files and leave at least one item in each group. The documentation recommends checking results before deletion: similar-word matching can cause false positives and slow scans, and picture comparisons can be CPU-intensive. dupeGuru is free, with packages listed for Windows, macOS, Debian, RPM, Arch Linux, and Ubuntu PPA.

Duplicate Files Fixer scans computers, external drives, and cloud storage for duplicate photos, videos, music, documents, and other files. It can compare file contents as well as names, size, creation and modification dates, and similar names, so identical files can be detected even when their names differ. Users can preview grouped results and choose what to delete; Auto Mark selects extra copies while leaving one in each group unmarked. Folder exclusions are available. On Windows, it can scan Google Drive and Dropbox after sign-in and folder selection. The free version scans unlimited files and removes up to 15 duplicates in one go; additional deletions must be made one at a time. The paid version removes all marked duplicates in one click. It is listed for Android, macOS, and Windows. The paid plan is €35.95 a year, billed annually at a discounted price; the page also lists €64.95 as the product price. PC deletions go to the Recycle Bin by default, but USB and network-drive deletions do not.
