Data guides
OneDrive: see how much data you have, then export it.
Pick a system to see two things: how to check how much data is in it, and how to export a copy. No form, no sign-in.

How to see how much data is in OneDrive
- Sign in to the Microsoft 365 admin center with an admin or Reports Reader role
- In the navigation menu, select Reports (if you don't see it, select Show all → Reports) → Usage
- On the Usage page, under Reports, select OneDrive
- On the report page, select the Usage tab
- Read the storage used chart, or select Export and total the Storage used (MB) and Files columns
Record total storage used across all OneDrive accounts; the report only includes users with a valid OneDrive license.
OneDrive’s official instructions
How to get a copy of your OneDrive data
- Sign in to OneDrive on the web
- Tick the circle check box on each file or folder (or the header circle to select all)
- Click Download in the top bar
- Save the .zip file (limits: 250 GB and 10,000 files per download)
Administrators can download user OneDrive content through the SharePoint admin center or Purview exports.
Files of former employees are kept only for the retention period set by your administrator.
These instructions are written by DataFrenzy from each vendor’s public help pages. Menu names can vary by plan and change over time; the official link on each guide is the final word. Screenshots come from each vendor’s own help pages and videos or, where noted, from third-party tutorials credited under the image; dashed outlines are illustrations, not screenshots. Looking up a size or preparing an export never sends anything to DataFrenzy.
