Open files with unknown file extension

You recently downloaded a file which seems to be 'unreadable' by your system. How are you gonna solve the problem? Let's say it's an exercise from your university in xqt format... what's the program to read such files? How about a software that integrates into context menu and shows you how to open files?

Here comes OpenWith to deal with those things, for almost any file on your computer, the OpenWith.org Desktop Tool will tell you what type of file it is, and show you free programs that will open the file. It will even download them for you!
