FILExt - The File Extension Source

Welcome to FILExt!
How Did I Get Here?

If you did not come here directly or via a search then it's likely that you clicked on a file that Windows did not know how to open, you then picked the "search the Internet" option from the dialog and clicked on the search link on the Microsoft page that suggested you come here (or to our sister site cknow.com) to do the search. Please understand that you did not come here because we installed some software on your system. FILExt only exists on the Internet and we don't install software on your system. Basically, you got here to search for the name of a program that uses a particular file extension.
