I could have done with this on Friday when trying to extract an inf file from an exe file for a printer driver – Universal Extractor extracts files from any archive – a great tool to have in the toolkit. This site also has links to peid, a utility which detects packers, cryptors and compilers (600 of them!) and ussf.exe which determines which switches can be used with a setup file. I really need to start keeping an eye on msfn more.
