DupSweep is one app that works seamlessly on both platforms. Find duplicate files, duplicated folders, and visually similar photos. Every match is confirmed with SHA-256. Deletions go to Trash (Mac) or Recycle Bin (Windows) โ undo anytime.

One app, one license โ pick the mode that fits what you're cleaning.
SHA-256 byte verification
Exact duplicates only, confidence-scored and grouped, with keep rules to auto-pick what stays.
Whole-folder clustering
Finds duplicated folder structures, not just files, and merges them safely with a full preview.
Perceptual hashing
Finds similar photos even when they're not identical: bursts, exports, resizes, chat copies.
Installers, AirDrop copies, setup files, zip extracts, and "final_final" exports that piled up next to the originals.
A Migration Assistant copy (Mac) or old PC disk (Windows) plus files you dragged over often leave whole folder trees duplicated.
If OneDrive keeps a folder on disk, add that folder to the scan. Same SHA-256 check as any other path. Make online-only files available offline first.
Near-duplicates from bursts, exports, and messaging apps. See the similar photos page for perceptual hashing.
USB disks and external drives work if mounted. Windows also scans network shares if they appear as folders.
Byte-for-byte verification + perceptual hashing. Nothing gets removed without proof.
Duplicate matches are confirmed byte-for-byte before anything is touched โ never just filename or size.
Finds whole duplicated folder structures, not just individual files, with safe in-place or copy-based merging.
Perceptual hashing (dHash + pHash) catches near-duplicate photos, not just exact copies.
Every deletion goes to the system Trash first, with full operation history and one-key undo.
Point DupSweep at your OneDrive folder and find duplicates the same way as on any other disk. Make online-only files available locally first, then scan.
