Help with getting windows explorer to open

[pitchinnate]

First of all, yes, I read the "please read this before posting" and I have tried exactly what it says and gone through other post and tried to figure it out also. Ok now for the problem. I am creating a application that auto runs when the CD is put in. That is working great no problems at all. I would love to have a button that when you click on it, it opens windows explorer to a certain folder. When I try the code posted which is:
drv = _url.substr(8,1);
getURL(drv + ":");
Firefox tries to open up the folder and displays it as folder only in a web browser as html. I think there is a way of doing it because I've seen other flash apps do it before. Any help would be greatly appreciated.
