Zip files   Some documents in this site are in a compressed format called 'zip'.

Zip files save time and space, and make downloading documents faster. They can also contain more than one document.

To be able to open and read the contents of a zip file you need special software such as StuffIt Expander. This is free and available for Windows, Macintosh, Linux and Solaris. It can be downloaded from the StuffIt Expander website.
