WinZip Self-Extractor is a utility that creates native Windows self-extracting ZIP files. These files are ideal for electronic file distribution because they can contain multiple compressed files, ensuring that important files do not become separated from the rest of the package. They also allow the receiver to use a familiar Windows interface to decompress files, without you having to own or know how to use a separate unzip utility, and they optionally run a setup or installation program, which may be included by the developer when the files are decompressed.

A self-extracting ZIP file is an executable program file (EXE file) that includes a ZIP file and software to extract the contents of the ZIP file. Users can run a self-extracting ZIP file just as they run any other program.

This version features support for self-extracting ZIP files spanning multiple removable disks, support for software installation running standard Microsoft-format INF files as an alternative to setup programs, support for self-extracting ZIP files that can open any file using the application associated with that file on the end-user's machine, and support for self-extracting ZIP files that both unzip and overwrite automatically.

WinZip Self-Extractor costs $49 for a license to create an unlimited number of freely distributable, royalty-free, self-extracting ZIP files.
