How to find duplicate files safely
Exact-match duplicate detection works best when the review step is treated as part of the feature.

The safest duplicate cleanup workflows rely on exact-match logic and explicit review. FileLever’s current duplicate finder behavior groups candidates by file size, hashes them, and confirms matches byte-for-byte before deletion logic is considered.
That approach matters because it keeps “duplicate” grounded in observable file identity instead of guesswork. Even when deletion is possible, it should remain an explicit user choice with a keep policy.
