What is a “compression” program?
Much of the software on the Internet is stored in a compressed format, which makes the software smaller and therefore faster to download. To use a compressed file after you’ve downloaded it, you need a de-compression program to expand it to its normal size before you can install or use it. NetDotCom includes the popular Windows compression programs WinZip on it’s CD. The most popular Mac compression program is StuffIt Expander. If you don’t have any of these programs, you may visit one of the software sites listed above and download one.
