Cool, yeah I was worried about the game not being in the computer's registry.
My reason for doing this is because I do not have the game's disc with me so I can't reinstall it.
I guess I'll try it out with copy and paste first and try to get the disc in the meantime.
Oh btw, reformatting is like a factory reset. You basically wipe off everything in the cpu and install them back. It's like getting a new computer!
