Oh god, you reminded me. I had a run in with this recently because my parents got new laptops. 1TB hard drive, should be plenty right? NO! My mom had 15GB of files in her home folders and One Drive was whining constantly to pay them for more space.

It was about an hour of debugging to keep the files safe, extract One Drive from the home folder locations because it had dug in like a virus, and then (after 20 online searches and scouring forums) click the specific toggle in the specific menu to disable One Drive so it would use local files.

I paid for a 1TB computer, why are you forcing me to use your shitty online-only limited-space shit show. Fucks sake.
