A USB flash drive is a storage device that plugs into the USB port of your computer. These devices often have a keychain attachment or lanyard that you can wear around your neck. They are useful for transferring files from one computer to another. When the files are no longer needed, you can delete them from the USB drive much in the same way that you would any other file on your computer. However, files deleted from a USB drive are not stored in the recycling bin of your computer.
Open "My Computer" under the "Start" menu.
