Universal Extractor is a program do to exactly what it says: extract files from any type of archive
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, or even a Windows Installer (.msi) package. This is still a work in progress, but so far it's proven quite useful and I feel others can also benefit from it.

I should stress that Universal Extractor is not intended to be a general purpose archiving software. 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 that I wanted 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. In the process I got a little carried away and ended up throwing in support for every kind of archive format I possibly could find.
