What Is a self-extracting EXE (SFX)?

>>CCZip Self-Extractor is a utility program that creates native Windows and DOS self-extracting ZIP files. These self-extracting Zip 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
  • Allow the receiver to use a familiar Windows interface to decompress files, without knowing how to use a separate unzip utility.
