This program works absolutely perfectly and quickly, doing exactly what it says it will do, without bugs or crashing or weird problems. So what's wrong with that? It's function is absolutely necessary and should really be built into OS X - on Windows it's a tweak offered by Microsoft as "send to anywhere" but this is better. Yes, it would be nice if it moved between volumes, but it DOES move within a volume, and it copies between volumes. I use this constantly and am very happy to have it.
