Have you ever been looking for something on a floppy disk? You stick the first disk in, hit the icon for your A: drive, discover it's not what you were looking for, then you stick the second one in, go back to the drive A: icon, hit it again, and on and on. Each time you insert a new disk, you have to click that A: drive to get the computer to update what's on the disk. Or do you?

An easier way is to hit the F5 key when you swap disks. It will refresh the contents without you having to bounce back to your A: drive every time.

Open My Computer and give it a shot.

Oh, I suppose we could all start labeling our floppy disks. Yeah, I guess that would work too (but it would take all of the fun out of things).
