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.
 
Games never come with RAR extensions so you must be using illegal copies and you won’t get much help here

Huh? I play skyrim, VIA steam, with mods that makes my game over 100GB+ so I made a backup incase it breaks one day and I can restore to a safe point.

I have more than 1 back up so I put them into rar so it can fit into the usb
 
I am sorry guys maybe I didn't clarify, the game is working fine now that I replaced with my backup, but the thing is that my C: drive is full too but I only moved the game from my external usb to E: which confuses me =l
