Mmmh.. I used the root folder just to test Vista's behaivior. And btw why
shouldn't I use the C: folder? I somehow got the weird attitute my OS should
do what I want and not hide files or even entire folders from me. On the
other hand, you get the feeling MS does not want users to look into certain
folders and to really administrate their own computer because they hide
entire folders by default!

But never mind, I fixed it :-). You can turn the whole "folder type" thingy
off by modifying the registry.

Thanks again for your answers,

Thomas
