Why would it result in 1 and go to 0%? Or do you mean in their case, not yours? The description you highlighted claims that when using "auto" moving should continue "until threshold is met". This must mean it should stop when "Free down" threshold is passed, no? I am in the process of setting up my own rules to keep as much new media on my cache as possible, and I just want to understand my options. I was thinking of going for 85% Move, 75% Free (10% = 400GB, so large files should be moved) and Auto on days.
