A Microsoft file hosting and synchronization service.
Hello,
Just to make sure we handle this right, are you trying to free up space on your physical laptop drive because you are out of room for apps and local files, or are you just trying to clear out your cloud files to stop that OneDrive full message?
They are basically two separate storage bins that get synced together. Let me know which space you are really trying to clean up so I can get you the exact steps without causing any accidental data loss.
