Two files with different names but identical bytes get caught. Same name, different bytes stay separate. Content decides, not the label.
No manual hunt through folders. Point FolderManifest at a drive or folder and hash every file in a single pass, then review the duplicate groups.
Remove duplicates, then prove the survivors are intact with a checksum manifest. Cleanup and integrity evidence come from the same scan.
The best duplicate file finder for Windows 10 groups identical files by SHA-256 hash instead of filename, scans an entire drive in one pass, and runs locally so private folders never leave your PC. FolderManifest does all three on Windows 10 and Windows 11, then exports a manifest you can review before deleting anything.
Filename and size matching misses real duplicates and flags false ones. FolderManifest computes a SHA-256 checksum for every file, then groups files whose hashes match. Two files with different names but identical bytes get caught; two files with the same name but different bytes stay separate. That is the difference between a guess and proof.
