Yes, over 22k extensions if you only count Windows and DOS extensions. They first started using something called the "8.3" convention meaning that the file name was eight characters and the extension three characters. Windows has since dropped the 8.3 convention and supports long file names. But there are other operating systems and programming languages that use more than three character extensions, such as UNIX, Macintosh, and JAVA... So there can be a bazillion kinds of extensions... -Steve Gregory- -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Ingemar Hernefjord (KC/EMW) Sent: Monday, October 30, 2006 7:46 AM To: [log in to unmask] Subject: Re: [TN] Question for Mr Yoda Theoretically correct, but I think Steve was closer to reality. I came to the same amount. Over 22k file extensions, isn't that madness! Must be tough even for a skilled hacker to handle.
