Info-Zip Open-Source Zip Utilities

Info-Zip is a simple open-source zip utility that uses the standard "deflation" algorithm.  It can be used to unzip the zipped programs we send out or to zip documents for faster viewing with SwiftView (which views zipped documents without unzipping them).  It runs at the command prompt by typing commands like "zip c: \sourcefile.pcl" or "unzip".  It is available for an incredible number of operating systems and the source code is free from the Info-Zip site.  Unfortunately, their website seems to move around a bit, so if you don't feel like searching for it, we offer the Windows versions of these utilities here for your convenience.

unzip.exe (expands zipped files)
zip.exe (compresses ordinary files)
zipcrypt.exe (compresses files so that a password is required to unzip them)
