Zipped files are files that have been compressed to use the smallest amount of memory possible. Zipped files are easier and more efficient to download, store, and send over the Internet or by e-mail. After downloading,"unzip" the file to have access to the individual items contained within it. To unzip the file, you need to use WinZip, an inexpensive Windows utility, or UltimateZIP, a free, downloadable program. If you don't have WinZip or UltimateZIP installed on your computer, visit www.winzip.com or www.ultimatezip.com.
