While several common programs support the 'Zip64 extensions' for archives containing files larger than 4GB, there remain significant real-world problems in using them.

HudsonAlpha Discovery developed this program to provide a simple unzip implementation that is useful on a variety of platforms. The program is modelled after InfoZip's unzip program, and takes many of the same command-line options.
This program is written in Python, and requires Python 2.6 to run. There are no other pre-requisites.
