Literally. I open up my terminal and try to cd Desktop only to be told that no such file exists. I thought for sure everyone this was happening to was just not reading something correctly and were foolish. Nope! It literally began deleting my files.
Edit 2: Even once it's done and you have them locally and not "on demand", the Desktop is in
~/OneDrive/Desktopinstead of~/Desktop. See this helpful comment.
It looks like there might be a way to sort of disable Files on Demand but it looks like it won't let me do it until it's done uploading? I'll post updates.
Not to be dramatic, but I'm really going through it. My mouse logitech mouse is suddenly chattering really bad and double clicking everything. Also while Steam refuses to let me disable auto updates for all games in any sort of easy way. And DDG seems intent on only showing me results related to launching games without updating (as opposed to merely disabling auto updates until I launch). The chatter fixer I found for my mouse does not work and the other requires some logitech program to even try to use. (The repo doesn't mention the name.) This is awful. When it rains it pours, I guess. Literally can't even high light this text to wrap it in a spoiler. This is fucking stupid.
Context: My parents have a family plan for Microsoft 365 they added me too and it has 1 TB of storage I can use. I wouldn't have turned it on otherwise.
Edit: My desktop background has literally vanished and turned solid black.
DO NOT ENABLE ONE DRIVE.
OneDrive is the devil. It symlinks the file structure on Windows and then moves all your photos and such into their chosen directory. If you uninstall it, it makes a half-hearted attempt to move them back, maybe, but will just do a random subset and give up.
After removal, you have to edit registry keys (obscure ones) to break Windows' connection to onedrive\pictures and such, or you end up with two pictures folders in your home dir.
So much more fail I can't even remember right now.
Another brick in the wall
