An honest answer to which one fits which job, and the sources we checked. ## When an alternative is the better choice - **dupeGuru.** Free, open source, and it runs on macOS and Linux today. Its fuzzy file-name and picture modes find near-duplicates that an exact-match tool deliberately will not. - **AllDup.** Free even for companies, runs on Windows Server, and finds similar images and audio as well as identical files. - **Duplicate Cleaner Pro.** If your duplicates are photos that were edited, rotated or resized, or music in different encodings, its similarity matching is built for exactly that, and one licence covers your own machines. ## When DuplicateDuster is the better choice - You want to be sure: before any copy is touched, DuplicateDuster reads it again from the disk and confirms the match itself, and refuses a batch that would leave no copy at all. - You need to show what happened: every cleanup leaves a report with both files and both hashes. - You want exact matches only — two files with the same SHA-256 — and a source folder the app is never allowed to delete from. - You would rather pay once: €20, VAT included, and scanning is free without limit. ## Sources - dupeGuru: [dupeguru.voltaicideas.net/](https://dupeguru.voltaicideas.net/) (checked 5 October 2026) - AllDup: [www.alldup.de/en\_index.php](https://www.alldup.de/en_index.php) (checked 5 October 2026) - Duplicate Cleaner Pro: [www.digitalvolcano.co.uk/dcpurchase.html](https://www.digitalvolcano.co.uk/dcpurchase.html) (checked 5 October 2026) Product names are the trademarks of their owners and are used only to identify the products compared.
