A self-extracting Zip file is an executable file (.exe) that contains a Zip file and a small program to extract (unzip) the contents of the Zip file. Users can run (execute) a self-extracting Zip file just as they run any other program: just double click on the .exe file.

WinZip offers two versions of our Self-Extractor program. WinZip Self-Extractor Personal Edition, which is included within WinZip, and WinZip Self-Extractor which is sold separately. For information on the differences between WinZip Self-Extractor Personal Edition and the full WinZip Self-Extractor please click here.

What are the Advantages to Self-Extracting Zip Files?

  • Self-extracting Zip files are ideal for electronic file distribution because they:
    • Optionally run a setup or installation program, which may be included by the developer when the files are decompressed
    • Provide easy distribution of one or more compressed files
    • Include sensitive information protected with 128- and 256-bit AES encryption
    • Create smaller files with LZMA, JPEG, PPMd, WavPack and Enhanced Deflate compressed Zip files (.zip or .zipx). (Note: LZMA, Jpeg, WavPack and .zipx support available in WinZip Self-Extractor 4.0 or later)
    • Designate custom high resolution icons for your Zip file (Note: Windows 7 and Windows Vista icon support available in WinZip Self-Extractor 3.1 or later)
    • 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 extract (unzip) files, without owning or knowing how to use a separate unzip utility, making them ideal for inexperienced users
  • Any folder information in the Zip file is automatically restored, including empty folders
  • When a self-extracting Zip file created by WinZip Self-Extractor is run, a dialog box is displayed. This dialog box makes it easy for the user to change the Unzip To folder and other options before extracting the files.
