For Mac OS and Mac OS X, what programs are available to make and decompress zip files?

Zip is a compression and archival format common to PCs. If you are using Mac OS X, the operating system itself compresses and decompresses zip files for you.

In addition, some utilities are available for creating and decoding zip and other types of archive files in Mac OS and Mac OS X:

• StuffIt: StuffIt Expander is a freeware drag-and-drop utility that can decode most compression and archive formats, including zip. To create zip archives, use DropZip, part of the StuffIt Standard Edition suite of applications. StuffIt Deluxe is a commercial application that can both create and unarchive zip files. All three applications are available from Smith Micro.
  
  
• ZipIt: ZipIt is a shareware program that can create and decompress zip files. It is available for Mac OS and Mac OS X, but if you have a version of the operating system earlier than Mac OS 8.6, you need to use an older version of the program. ZipIt is developed by Tom Brown.

If you are using Mac OS X, the Unix zip utilities are also available from the Terminal application. See In Unix, how do I create or decompress zip files?
