WinZip Self-Extractor 3.0 creates self-extracting Zip files. These self-extracting Zip files are ideal for electronic file distribution, because they:
- Can contain multiple compressed files, minimizing download time and ensuring that important files do not become separated from the rest of the package
- Allow the receiver to use a familiar Windows interface to decompress files without a separate unzip utility
Additionally, self-extracting Zip files can optionally run a "setup" or "installation" program, provided by the creator, after the files are decompressed.
