While several common programs support the 'Zip64 extensions' for archives containing files larger than 4GB, there remain significant real-world problems in using them. Because the zip format is informal, there is disagreement between implementers on what a valid zip file looks like. Even when programs agree, many common operating systems are slow to provide recent versions of the software.
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.
Download the distribution and
extract it with tar -xzf
. Change into the extracted directory, and run
python setup.py install
(this command will most likely require superuser privileges; more options
are described on the Python Distutils Installation page).
unzip.py file.zip
from the command prompt. More help is available by running
unzip.py -h
