I Can't map an extension in Windows NT. It says Extension in already used but It isn't found in File Types. Where else do I look?

Unfortunately I have experienced this problem before. The extension is already being used. It won't show up EXactly in file types, but if you click on file types, and choose a certain file, you might seee that it has more than one extension associated w/ that file type. Look through each of them carefully, it will be there.

Do it manually. At a command prompt, type "assoc .ext=C:\somepath\someprogram.exe"
Let me know...

Ooops, I got the assoc wrong, its a class not a program path. Another way to do it is Shift+RightClick on the file and choose Open With...select the program you want and select the box that says Always use this program....

Sorry for the misguidedprevious post... ;-(
