Frequently asked questions
Before you use this tool
Is the Duplicate Keeper Advisor free to use?
Yes. You can use this tool in the browser without creating an account or installing software.
How accurate is the Duplicate Keeper Advisor?
The recommendation follows conservative file-management rules, but it cannot inspect your actual permissions, retention obligations, version history or business context.
Can this tool delete or change my cloud-drive files?
No. This page does not connect to your cloud account and cannot rename, move or delete files. It produces an estimate, analysis or checklist for you to review.
What should I do after using the Duplicate Keeper Advisor?
Confirm the recommendation in OneDrive. The advisor cannot inspect permissions or versions; its result is guidance, not an automated decision.
