What Puntomaus said. I like to keep my main runtime lean and mean. (It may just be my imagination, but Poser seems to run faster that way.) I have very little in it except the original Poser 5 content. Each DAZ character has its own runtime. But I do copy the !DAZ folder to the main runtime. You have to remember to do this whenever you install a new DAZ character, or apply an upgrade or SR for an existing one.
