Windows 95/98/NT has a nasty habit of adding ".txt" on to
any text file you are editing. When you look at the
directory of files you will see "USER.LST" even though
the actual filename is "USER.LST.TXT". To make windows
honest you need to follow these steps:
1) Double click on "My Computer"
2) Double click on "C: Drive"
3) Choose "Options" or "Folder Options" from the "View" menu.
4) Click on the "View" tab.
5) Uncheck the option called "Hide file extensions for
known types / registered file types". The wording of
this option changes depending on the flavour of Windows
you are using.
6) Click OK.
Now go back and you will see that the file was actually
named "USER.LST.TXT". Change the name to "USER.LST" instead.
