I made an error in my previous message. It should have read:-
I have received several files as e-mail attachments with Outlook Express which are in "dat" format. I have saved them and tried
several ways, Notepad, Wordpad, Microsoft Works, to open these with no success. Is there a way to open these files?
All these files are ATT0000 type.
The error was "data" unstead of "dat"
