Universal Extractor is a program do to exactly what it says: extract files from any type of archive, whether it’s a simple zip file, an installation program (like Wise or NSIS), or even a Windows Installer (.msi) package.
This application is not intended to be a general purpose archiving program. It will never replace WinRAR, 7-Zip, etc. What it will do is allow you to extract files from virtually any type of archive, regardless of source, compression method, etc. The original motivation behind this project was to create an easy, convenient way to extract files from installation packages, such as Inno Setup or Windows Installer packages, without pulling up a command line every time.
I have also written an article How to Make Any Portable Application with the help of Universal extractor.
