The PostScript files are zipped and can be unzipped with a unzipping program like gzip (UNIX) or winzip (Windows). A free trial version of winzip can be found at www.winzip.com
After unzipping the file, you need to open it in a viewer that is capable of handling the PostScript format. I recommend the GSview and Ghostscript programs which can be downloaded free of charge from the Ghostscript home page of the University of Wisconsin.

The GSview program can also handle .PDF files but alternatively you can download Adobe Acrobat Reader for free.



Note: some documents cannot be read with older versions of GSview or Acrobat Reader. If you encounter this problem, update your program. If the problem persists email me at the address below.
