Bulk delete duplicate files in OneDrive with one reviewed cleanup pass
ClearCopies scans OneDrive read-only, groups exact duplicates by byte size and matching quickXorHash or SHA-1 fingerprints, and lets you review every group before anything moves. When you confirm, a single cleanup pass moves the approved copies to the OneDrive recycle bin — still recoverable, never permanent. Every benchmark figure on this page comes from one production OneDrive scan.
Why deleting duplicates by hand doesn't scale
One production OneDrive scan indexed 102,610 files across 584 GB and surfaced 16,718 exact duplicate groups. At that scale, hand-picking copies in the OneDrive web interface stops being an option.
16,718 groups is not a to-do list
Reviewing each group by hand in the OneDrive interface means opening folders, comparing copies and deleting them one at a time. At that volume, the job stretches into days of repetitive clicking.
Sorting by name proves nothing
OneDrive can hold identical content under different names and different files under the same name. Without a content fingerprint, manual sorting mixes real duplicates with look-alikes — and byte size or dates alone are never proof.
Manual deletion leaves no trail
Hand-deleting thousands of files produces no plan, no record and no receipt. If a file you meant to keep goes missing, there is nothing to audit — and no systematic guarantee that one copy of every group was retained.
From 102,610 files to one reviewed cleanup pass
The workflow separates evidence, decision and action, so a bulk cleanup never turns into blind deletion.
- 01
Scan OneDrive read-only
Connect OneDrive; the scan only reads. ClearCopies indexes byte sizes, paths, timestamps and the quickXorHash or SHA-1 fingerprints Microsoft Graph already exposes — file bodies are never downloaded.
- 02
Review the exact groups
Duplicates appear as groups with folder paths, sizes, timestamps and sharing state. Files count as exact only with identical byte sizes and a matching fingerprint of the same algorithm; you choose the keeper in each group, and at least one copy is always retained.
- 03
Run one cleanup pass
After a one-time payment, ClearCopies moves the approved copies in a single pass that scales to thousands of files, revalidating each one against live metadata immediately before it moves.
- 04
Recover anything from the recycle bin
Approved copies land in the OneDrive recycle bin, recoverable for the retention period Microsoft applies to your account. You get a progress report and a receipt of exactly what moved.
What keeps a bulk cleanup safe
Moving thousands of files demands stronger guarantees than a manual delete, not weaker ones. These rules apply to every cleanup pass, whatever its size.
Nothing moves until you pay
The free scan only reads and never changes your files. Files move only after you review, confirm and pay for a cleanup.
A keeper in every group
At least one copy is always retained in every group — by design, a cleanup cannot empty a group. Shared or protected items are surfaced for manual review instead of being auto-selected.
Recycle bin only, after revalidation
Every selected file is checked against live OneDrive metadata immediately before it moves; anything changed or missing is skipped. Approved copies go to the recycle bin, where they stay recoverable — ClearCopies never deletes files permanently.
One-time pricing, sized by recoverable space
The free scan measures exactly how much space is recoverable, and that number sets the price: $9.99 up to 25 GB, $19.99 up to 250 GB, $39.99 above 250 GB. The 22.4 GB found in the production benchmark, for example, falls in the $9.99 tier.
Every cleanup is a one-time payment — no subscription. The scan and full review are free, and your exact price is shown after the scan, before you commit to anything.

How do I bulk delete duplicate files in OneDrive?
Run the free read-only scan, which groups exact duplicates by byte size and matching quickXorHash or SHA-1 fingerprints. Review the groups, choose the keeper in each one, then confirm a single cleanup pass. ClearCopies moves the approved copies to the OneDrive recycle bin — nothing moves before you review.
Can I delete thousands of duplicate files in OneDrive at once?
Yes — one cleanup pass scales to thousands of files. In a production OneDrive scan, ClearCopies indexed 102,610 files and grouped 16,718 sets of exact duplicates for a single reviewed cleanup. Each selected file is revalidated against live metadata immediately before it is moved.
Do the deleted duplicates go to the OneDrive recycle bin?
Yes. Every approved copy is moved to the OneDrive recycle bin, where it remains recoverable for the retention period Microsoft applies to your account. ClearCopies never deletes files permanently.
How does ClearCopies know two OneDrive files are exact duplicates?
Two files are grouped as exact only when their byte sizes are identical and their content fingerprints — quickXorHash, or SHA-1 where OneDrive provides it — match under the same algorithm. Matching names or dates are never treated as proof, and files without a comparable hash are left for manual review.
How much does it cost to mass delete OneDrive duplicates?
The scan and full review are free. If you decide to clean, it is a one-time payment based on recoverable space: $9.99 up to 25 GB, $19.99 up to 250 GB, and $39.99 above that. There is no subscription, and you see your exact price after the free scan.
Is it safe to bulk delete OneDrive duplicates this way?
The design assumes mistakes must be recoverable. At least one copy is always retained in every group, shared or protected items are surfaced for manual review instead of being auto-selected, and approved copies go to the recycle bin rather than being permanently deleted. You can also export the cleanup plan for free as an audit trail.
