WinZip Self-Extractor 3.1 creates self-extracting Zip files. These
self-extracting Zip files are ideal for electronic file
distribution because they contain multiple compressed files
minimizing download time and ensuring that important files do not
become separated.

Additionally Self-Extractor allows the recipient to use a familiar
Windows interface to decompress files without a separate unzip
utility.

Self-extracting Zip files can optionally run a setup or
installation program provided by the creator after the files
are decompressed.

WinZip Self-Extractor 3.1 is a companion product to WinZip and is
separately licensed. The current release of WinZip contains WinZip
Self-Extractor Personal Edition a subset of WinZip Self-Extractor
