Yes. OneDrive storage is separate from the storage on the PC.
A new computer can have plenty of disk space and still show a OneDrive storage full warning because OneDrive has its own storage quota. When OneDrive is over quota, files in OneDrive become read-only, and new files may stop uploading or syncing.
Safest way to stop using OneDrive without losing files:
- Check whether files are only in OneDrive or also on the PC
Open File Explorer and open the OneDrive folder. If files show cloud icons, some may be online-only. - Make files local first
For anything important, copy files from the OneDrive folder into normal folders outside OneDrive, such as Documents, Pictures, or another folder under the PC user profile that is not inside OneDrive.
This is the important safety step: files moved out of OneDrive are no longer backed up there, and if they are deleted from OneDrive later, the local copies outside OneDrive remain. - Turn off OneDrive folder backup
Select the OneDrive cloud icon in the notification area > Help and Settings > Settings.
In Sync and backup, turn off backup for folders such as Desktop, Documents, and Pictures if they are being backed up. - Unlink the PC from OneDrive
In OneDrive Settings > Account > Unlink this PC > Unlink account.
This stops syncing. - Hide or uninstall OneDrive if no longer needed
- To hide it: File Explorer > right-click OneDrive > Properties > check Hidden, then quit OneDrive.
- To uninstall on Windows 10/11: Start > type Programs > Add or remove programs > Microsoft OneDrive > Uninstall.
About deleting files from OneDrive:
- If files are still inside the OneDrive folder and syncing, deleting them from OneDrive can also remove them from the PC copy.
- If files have first been copied or moved to folders outside the OneDrive folder, they can then be deleted from OneDrive online to free cloud space.
- After deleting from OneDrive, the OneDrive Recycle Bin also uses storage, so emptying it can free more space.
Useful facts:
- OneDrive storage includes OneDrive files/photos and items in the OneDrive Recycle Bin.
- Uninstalling OneDrive does not by itself delete files from the account; files can still be accessed by signing in to OneDrive on the web.
If the goal is simply to stop the warnings and keep everything on the PC, the safest order is: copy files out of the OneDrive folder first → turn off backup → unlink the PC → uninstall OneDrive if wanted.
