On MS-DOS/Windows, its the last part of the dotted filename, ie junk.txt would be a text file of junk.c would be a C cource file. Most Unix's are the same. The extension is the last component in a period separated name. I believe that on MacOS, BEOS and others, the extension information is stored separately and not part of the name or may optionally be part of the name. That's also how web servers and web browsers know what to do with files that have an html extension. Unfortunatly, if the file being transported by the server or the browser has a 'known' extension, the file will be processed by one or the other or both. Once the file is processed, you can't save a copy that's identical to what was sent. This is particulalry true as extensions do not have to be unique. I've seen two or more applications use the same extension and conflict with one known by a web browser. Click on the link and you can't download the file, you just get junk on the screen. -- Richard Shetron [email protected] [email protected] NO UCE What is the Meaning of Life?
