Just a little curious here, why will DVD movies and CDs manufactured open automatically, yet if I have a data CD I have to go to my computer and open it manually? I hope this makes sense to someone.
It`s the Auto Run feature of Windows.
Look inside the discs and you will find a file called [autorun.ini].
Windows reads this file and automatically starts the program specified.
You can make a data CD to Autorun by setting it when you burn it.
Or, do you mean that a folder opens?
If so, then that is a different part of the Auto Run feature.
Go to your drives property window and select the Auto Run tab.
You can change what the computer does when you insert different types of discs.
