I had this problem eons ago...lets see if I remember......
Open notepad from start menu, type stuff,
Select SAVE AS,
select "all Files *.*",
retype name as Description.ext
click save.
Doing it in that exact order, I believe.
I used to right click in a folder and make a txt file, then open it. I found that much more difficult to save than opening notepad from the start menu.
If it STILL doesn't work for you, a rarity,... then try using one of the many free scripting programs out there.
I use Crimson Editor, because I am so used to it, but there are MANY others.
