How do I use a jump drive Hi-Speed 16 GB Stix

You didn't mention the manufacturer on your 16GB stick, but that should not be a problem using it. The price on 16GB USB drives has fallen dramatically in recent weeks, so you will see more of them in use.
If you plug the USB drive into one of your computer's free USB ports, it should be recognized by your computer and assigned a drive letter in Windows. This means if you view the contents of your hard drive using Windows File Explorer, you should see another drive representing the 16GB USB thumb drive in the list of disks.
If you click on that drive you will see its contents (if any). Some drives come with software pre-loaded on them which you may be able to use to encrypt the contents of the thumb drive.
In all other respects, the USB drive will function like any other disk drive, allowing you to move or copy files back and forth between your main hard drive and the USB drive.
Be careful to 'unmount' the USB drive before you remove it from the USB port. Often there will be a flashing LED light on the drive which indicates that data is being written to the USB drive. If you remove the drive while the light is blinking, you may damage the file system on the USB drive and make reading its data impossible.
To eject the drive properly using Windows File Explorer, click on your main hard drive (usually C:) to select it, then RIGHT-CLICK on the drive you want to eject. A menu will come up, and you should click 'Eject' to close out the USB drive. You will get a confirmation message window that it is safe to remove the drive.
