to open Windows Explorer, right-click and select "Properties"
In the "Target" box I have the following;
C:\WINDOWS\EXPLORER.EXE /n,/e,D:\My Documents
This opens with the "My Documents" folder expanded, (which I have on the D: drive) You should be ablse to adjust your details to suit.
(I have Win 98se. I assume it's the same for other flavours?)
I hope this helps,
