So my C: drive is a small SSD meant just for my os while my E drive is a HDD which is for my games, so I plugged my usb, open the game.rar and waited for it to read then copy the folder onto my E: drive, later I got a prompt that says I don't have enough memory on my C: drive and it went from empty to full while my game was perfectly copied to my E drive... I am kinda confused and don't know why my C: drive is affected.
