I've been dealing with this for years. Between Samsung Gallery syncing to OneDrive, Google Photos backups, and the occasional app reset that re-uploads everything - duplicates pile up fast.
WhatsApp makes it worse. Share a photo with someone? Now you have the original in Camera Roll AND a copy in WhatsApp Images - both backed up to the cloud. Receive photos from family? Auto-saved to gallery, then backed up again. The duplicate math adds up quickly.
Manual cleanup is tedious. Desktop tools exist but require downloading everything first. Cloud storage providers don't offer built-in duplicate detection.
OneDrive has no built-in duplicate detection.
OneDrive MediaOps fixes this. First Android app to detect duplicates entirely in the cloud:
- Scans without downloading files
- Perceptual hashing catches visually identical photos
- Preview before deleting
- Batch delete to reclaim storage
Built from personal frustration after manually deleting hundreds of duplicates.
