How do I get a count of UNselected bytes in status bar?

I've modified my status bar to show me (via a bar graph) if the currently selected items will fit on a DVD {bg+...v=sba/4.2g}. What I would like to do is have another bar graph tell me if the unselected items will fit on a DVD, either via a status bar code or by using rudimentary maths (eg v=(tba-sba)/4.2g).

Is this possible, if not, am I missing an easy work-around?

Thanks,

Justin

There's only total and selected counts, unfortunately.

Inverting the selection is the easiest way to get the size of everything unselected. By default the middle-click action of the 4th toolbar button does that, but you could bind the same thing to another button or hotkey to make it easier to access if you want to use it a lot.

Ok, that's what I thought, just checking I hadn't missed anything.

Thanks,

Justin
