DupeCleaner — Find & Remove Duplicate Files
Got the same photos, documents, or downloads saved multiple times across your folders?
DupeCleaner scans any folder (and subfolders) and finds files with identical content
— even if you renamed them — so you can safely delete the extras.
✔ Matches by real file content (SHA-256), not just filename
✔ Preview every duplicate group before deleting anything
✔ Automatically keeps one copy, flags the rest
✔ Scans subfolders too
✔ Works on Windows, macOS, and Linux
Requires Python 3.8+ (step-by-step guide included for beginners).
