what are you talking about. what a weirdo

what are these files? like powerpoint slideshows?

if you have two monitors plugged into a video card with two outputs, or two monitors plugged into two video cards, then each monitor is independent, and you can move windows between them. they are not just mirrors of each other. windows fully supports this and you don't need any other software.

matt's right, a splitter is the wrong connection configuration. you need either a dual-head video card, or two video cards. when it comes to a laptop, the best setup you can normally do is use the LCD screen on the laptop as one monitor, and then plug a monitor into the dvi/vga out and configure it as a separate monitor. not sure if docking stations actually add a second head.
