Copying files to a USB flash drive is very simple. All you need to do is plug it into a usb port on your computer. After you do that click on my computer and under devices with removable storage there will be an icon representing your flash drive, double click on that icon to open up a window. Once that is done just copy and paste the files you want on the flash drive into the window and they will be on the flash drive. You know all your word documents in the palm of your hand.
