E.g. file ABCDEFG.XYZ. XYZ is the file extension.

For more info we'll need to see the exact full name of the file you're asking about.

Actually I've yet to read that a file extension is invalid.

There is no rule in Windows that the .CNET files are invalid. So help.cnet is a valid file and extension. That said it could be invalid to open those with Word.
