C.B.
We boughst a half terabyte back up drive from Amazon. You plug it into the USB port and the computer recognizes it and pops up a window that has many options. You choose "view files". Or if a window does not pop up you can go to "Start" then click "Computer" and then click on the external drive to open it. Here is the one we bought.
