When your PCs hard drive begins to fill up, instead of deleting excess data many people simply purchase a large external USB drive. Modern external drives ship with a huge amount of memory for minimal cost so it's a viable solution; the only trouble is keeping track of all the USB devices connected to your machine. These devices could be scanners and printers or your mouse and keyboard, either way you won't want to pull out your USB cable if you're not sure of which piece of hardware it's connected to.
