Universal Extractor extracts files from any type of archive, whether it is a simple ZIP file, an installation program, or even a Windows Installer package (.MSI). The program is still under development, but has proved very quickly that it can be very useful.
I must emphasize that Universal Extractor is not intended to be the main application for working with archives. It will never replace WinRAR, 7-Zip, etc. What it does is only allows you to extract files from virtually any type of archive, regardless of source, compression method, etc.
