Could i copy an installed game's folder and paste it to the other hard drive i have?
So i format windows and then copy and paste it again to the freshly formatted driver?
It will work ?
Depends. If its a steam game, most likely yes. If not then it depends on the game. Some game require things to be exactly right, like registry entries that aren't there, etc.
