Open file on plug-in USB

Can anyone tell me how to open a .jar file when you plug your USB in a laptop? Write a batch file? Or what do I need?

I've read about it that it's only available on windows, so it's not possible on a MAC. But isn't there a way to open a window on mac, and say 'click here to start'?

So this questions has 2 parts:

1. How can i open a file when I plug in a USB on windows?
2. If it's not开发者_运维问答 available on mac - what other possibilities do i have?

Thanks!

For windows you're probably looking for AutoRun.inf. Though remember that this might have been disabled on the computer.
