STZip is a program that allows you to compress and decompress
files, i.e. to reduce their lengths. You saves space on your disks and reduce the transmission time if you send the files by modem. It also allows you to group several files in one single file, whose extension
in general is ZIP.
STZip uses files that are compatible with PKZip 2.04 on the IBM PC, and the Unix Info-Zip programs Zip 1.9/Unzip 5.0.
