thats the whole point of a virtual drive though, its virtual so it isnt realy there, therefore when you mount a .cue/.bin on it its isnt using any space at all on your hdd, basically its exactly the same as burning it and installing from a cd, when you put the cd in your cd player your not using any space on your hdd until you install, well its exactly the same with a virtual drive, you should give it a try, ive done it your way many moons ago and i must admit this way is a hell of a lot easier esp when you can burn it straight away if you have alcohol installed, which is imo the best burner/organiser/virtual drive application out there, better than nero/clonecd and daemon tools.
