Zip

Zip is a utility that compresses text files. It is often coupled with unzip, which extracts the compressed files from an archive (.zip file). GNU have an open source version called gzip / gunzip. Often, .zip files are sent via email as a poor man's FTP. IBM i does not provide a native zip / unzip utility, so we typically install a PASE version.

Java can be used in a pinch because .jar files are actually an archive (.zip file) of the class files.
