Things You'll Need
Instructions
Insert the memory unit into "Memory Unit Slot A" or "Memory Unit Slot B" on the Xbox 360 console. These slots can be found underneath the disc tray. It does not matter which one you select.
Turn on your Xbox 360 console with no game in the disc drive.
Press the center Xbox 360 logo button on the Xbox 360 controller, which should prompt a menu to pop up.
Scroll to the right using the left joystick until you reach the "Settings" tab. Scroll down and select "System Settings."
Scroll down and select "Memory." This screen will show you how much space is remaining on your memory unit as well as allow you to delete unwanted files, which will free up space.
During a game, when asked to save or given the option to save, select your memory unit on the screen that pops up to save your game to the memory unit.
