Frequently asked questions

Before you use this tool

Is the Transfer Time Calculator free to use?

Yes. You can use this tool in the browser without creating an account or installing software.

How accurate is the Transfer Time Calculator?

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 Transfer Time Calculator?

Use off-peak bandwidth for large migrations. OneDrive throttling, latency, small-file overhead and Wi-Fi quality can make transfers slower.
