I don't but can't you get the program to change the option of not showing the extension when you start it and then restore this option to the way it was when the program ends.
I'm not sure I understand... why wouldn't you want it to show the extension? I can disable it in explorer, but Java shows the full path and extensions, regardless of how explorer is set.
