Nancy, I was frustrated, too, but then I remembered that this WAS possible in earlier Windows versions. If you are running 7 (me, too), then you won't be able to do it. This is one thing I've seen others griping about with 7. All told, though, I like 7 enough to be happy that I switched (plus my computer is screaming fast now, so who can complain? ;-) ). You can make a new folder inside each kit folder, then leave out just the preview (put everything else inside the folder). When you go back up a level, and choose to view with medium, large, or extra large icons, you will see most of your preview page, probably at least enough to jog your memory...
Good luck, and hang in there! I started this in December, and every day I am amazed at how much more I know already. It IS a steep learning curve, but we can climb it!
