So, I was trying to make my HD be my Files directory, so I won't have to worry about running out of SSD space, where Windows and Pop OS are installed. (already running low on space).
But for some reason I though I could share EVERYTHING. MUAHAHAHAHA. But apparently sharing a steam library, phyton enviroments, and all of my files was not a good idea... Who would have though!! -_-
Steam games would keep re-installing themselves, and Windows permissions got so broken I kouldn't create a text file inside the HD.
Two hours of troubleshooting later, fixed it with "icacls \setintegrityLevel Medium"
I'll just share my save files for now...
