The reason this is a problem is because I like to download mods and my C drive has no room for that (I can't remember how much GB of custom content I had before I removed it but it was A LOT lol), and I think it caused my game to 'run out of memory', I'm not sure what that means but I started to get popups about that when playing the game.
I installed the sims 4 on my D drive where there is available space (This PC/New Volume(D:)/Program Files(x86)/Origin Games/Sims 4) but when I started the game it created a new Electronic Arts folder in my C drive (This PC/Local Disk C:)/Users/Shallon/Documents/Electronic Arts/Sims 4).
