This article is about creating a self-extracting zip file with WinZip.

"A self-extracting zip file enables your computer to unzip zipped files without installing any new software. The zip file gets converted to an exe file which once opened, unzips the contents to a predefined destination folder or a destination of your choice."

Microsoft Windows has also included the ability to open zip files in it's operating system. Users with XP and above do not need to worry about having winzip or winrar installed.

A caveat of choosing EXE for self extracting zips is that you will rarely find a mail host will allow these files to get through. Also, with an EXE a user may be more afraid to open it, since malicious code can execute immediately on opening.

With a ZIP file on the other hand, you can view the contents before you install them to your computer.
