What is the Zip compression format and how do I use it?
File compression is used to share large files or package several files together into one file. The most common file compression format on Windows computers is the Zip format. Most Macs already have Aladdin’s Stuffit Expander (http://www.stuffit.com/expander/), which opens many types of compressed files, including Zip When Mac users compress large files or want to send several files together compressed as one file, they commonly use the .sit (Stuffit) or .hqx (binhex) formats. Windows users do not normally have the software to open Sit or .hqx files, however, so Mac users are better off using the Zip format instead. Mac users can use the shareware program ZipIt (http://www.maczipit.com/) to create Zip files.
