Why would you wanna do this?
Answer #2
Because i need to save up some space on my other pc since it’s capacity isn’t big enough , and i don’t have enough budget to get a new hard disk. and some people said it’s possible to play games on sharing, but i just don’t know how, i’ve already tried it my self and it didn’t work..
