If you regularly use USB sticks and external hard drives on your computer, you have already noticed that each device takes a letter of the alphabet to identify it. For example, if you have a system disk C: and a DVD drive in D:, the first USB device plugged in will have the letter E:, the next F:, etc. The order of the letters depends on the order of connection of the disks and keys, which means that the same USB key can one day be on E and the next day on G.
