This would, in my opinion, be a useful thing.  I found several simple 
knapsack implementations; one of which is at 

What would be very useful is to dynamically load the knapsack based on 
size of whatever USB drive you just plugged in; so if you have say 4 
32GB drives, a 128GB drive, and a 64GB drive, the filling would be 
efficient no matter which order you plug the drives in. There have been 
several times I have wished for such a utility; I had one for the old 
TRS-80 LS-DOS 6 when I ran a TRS-80 Model 4 with a 20MB hard drive to 
copy to floppies, even when the floppies might have a different amount 
of free space.

I've done the multi-floppy tar thing back in Xenix days, and that was 
painful to say the least.
