AllDup vs Duplicate Files Fixer

AllDup has no write-up on Specifiction yet; its figures are above.

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.
