So I clicked unlink this pc and signed out of one drive, but the files are still taking up space on my pc. I went in to manually delete them and they showed that they were being deleted, but it’s still showing 290 taken up by one drive on my C drive.
@Elitealice I'm having the same issue - my local OneDrive folder was taking up almost the entire C: drive (475 GB), so I unsynced and disconnected from OneDrive.
File Explorer --> Properties for the C: drive still shows C: as being full
Once the local folder was disconnected, I verified that deleting files locally did not delete them from OneDrive, then deleted the local OneDrive Folder entirely, but Properties still shows the drive as being full.
