I want to create an interaction like that: when users click on a button, the My
Computer window will be opened to view a file's location on the hard disk. So
what is the suitable statement(s) should I use? I've tried
'open("D:\Studying\Director")' but it doesn't work.
Please help me!!

You have to tell it which program you want to open... in this case, it
would be explorer.exe. So the command would look like this:

open("explorer D:\Studying\Director")

Thanks you so much!
But it only works with Director MX 2004. I've tried that command with Adobe Director 11 and nothing happen. :-??

That is odd. I guess it won't work on Vista. Bummer. You can do the
same thing with BuddyAPI, and it does work on Vista.

baRunProgram("explorer c:\","normal",0)

Just FYI, you can do the same thing with Buddy API?s baOpenFile method. Just
give it a folder path but don?t include the filename. Way back in the day this
was cross platform compatible but it?s been a long time since I?ve checked if
it still works on a Mac. The other neat thing about this is that you can use
one script to open both files and folders depending on the path you feed it.

Thank you ! ^-^
