Hey Cheryl
I think your computer needs to be Windows ME or XP, or Apple OS X.
A zip/unzip program is an ESSENTIAL tool. Especially, for you because you use the internet alot. The ZIP file format allows you to "smush" a file so that it takes up less space on your hard drive. It also allow you to "make a copy" so you can put the original someplace else. I think you can get WinZip online. When you do get the WinZip, it appears as an open file folder on the desktop with a zipper down the middle of it. You click on that file to open things..
Your sis
