Add media type for autoplay feature in WinXP

Hi,

I would like to know if it's possible to add a media type for Autoplay
in WinXP and if yes, what would be the registry keys to modify.

I liked to do that because I have some .doc and .xls on a CF card and
when I insert it in my laptop, Autoplay call a batch file that copy
the content on the CF card to the harddrive. The only problem now is
that Autoplay recognize only pictures, video and music files.

So when I insert my CF card, Autoplay just open the folder. I have to
create a fake music file for example on the CF card and associate my
batch file with the music files handler. But that's a bit annoying. I
will have about 20 to 30 CF card and I'd like to Add a media type to
Autoplay that will recognize text files.

thx
