If there has been a revolutionary invention in the last few years, it is the USB memory, to store and transport large quantities of data in a small pen drive. It has become the star support for almost all users.
But it does suffer one inconvenience: you can`t create Autorun functions in it (like you can on CDs and DVDs).
But this is what APO USB Autorun 1.6.2.0 lets you do. You can do everything you would on a CD/DVD in a USB device, like autorun menus, automatic running, etc, modifying the Autorun.inf file (which the computer reads each time you insert the USB device).
