Is it possible to divide my 8GB memory stick so I only use 4GB for my Xbox (+

[IDIOT]

Marketplace exclusive content)? I have an 8GB memory stick but I only want to use 4GB for my Xbox to back up my gamesaves and pre-order exclusives (so the things not available on the marketplace).

When I partition it, I'd like to have 4GB for the Xbox (game saves and pre-order exclusives) and 4GB for my computer files. Is there any programme I can use to seperate the parts?

Microsoft makes their memory sticks so your ARENT able to do this. Correct me if i am wrong though because from my experience you cant do that.
