(HELP!) I need to bring in a Powerpoint presentation to school...?

USB Drive is what you call them. Once you plug it in, you will see an icon appear on your taskbar icons where your computer's clock is. Before you take out the drive, make sure you click on that icon and click on "Safely remove hardware". Wait for the computer to allow you to remove it safely. I used to not do that and it ruined my drives. Ended up losing some important data too.
