Frequently asked questions
Before you use this tool
Is the Duplicate Storage Cost free to use?
Yes. You can use this tool in the browser without creating an account or installing software.
How accurate is the Duplicate Storage Cost?
The arithmetic uses the values you provide. Its usefulness depends on whether those inputs represent the real drive, team or transfer conditions, so treat the result as a planning estimate.
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 Storage Cost?
Compare the result with cleanup effort. Microsoft 365 licenses are often quota-based, so this is an allocated-cost model rather than a billing forecast.
