A USB drive is an easy-to-use device for transferring files from computer to computer, but when drives are full or the files are no longer needed, you may want to clear everything off them. There are two methods for clearing data off of a USB flash drive -- formatting the drive or just manually deleting all the files. Both methods can be performed quickly the next time you need an empty drive.
Insert your drive into a USB port. Wait for the computer to read the drive and load the content. Click the Windows "Start" menu, click “Computer” and open the flash drive.
