Q. I deleted files from OneDrive, but my OneDrive storage usage hasn’t decreased. Please tell me how to permanently remove data and free up space.
A. Please delete the Version History (backup versions of updated files) using the steps below.
OneDrive counts file sizes including version history (backup copies of updated files) toward your storage quota. Files saved to OneDrive are set up to save a version history each time they are updated. You can restore previously edited versions from that version history.
Reference: Version history overview
【How to check file size】
- Sign in to Microsoft 365 Copilot Home and open OneDrive at https://thersacjp-my.sharepoint.com/.
*If prompted to sign in, please sign in with your THERS account.
- Click the Settings (gear icon) in the top-right corner of the screen, then select "OneDrive settings".
- Select "More Settings", then click "Storage Metrics".
- Select "Documents".
*The folder above corresponds to OneDrive's "My files".
- Please check the total "% of Site Quota" value from the list.
【How to delete Version History】
- Click "Version History" next to the file you want to delete versions for.
- In the Version History list under Modified, open the dropdown menu for the version you want to remove and select Delete. (Because the item is moved to the Recycle Bin, the deletion is not yet final.)
*Cannot delete the most recent version history.
*To delete all version files at once, click "Delete All Versions."(Because the item is moved to the Recycle Bin, the deletion is not yet final.)
*Cannot delete the most recent version history.
- Delete the Version History files from the Recycle Bin.

- After deleting the files from the Recycle Bin, open OneDrive at https://thersacjp-my.sharepoint.com/ in Microsoft 365 Copilot Home and check the available storage.
