Cindy, I did what you're doing, breaking up my runtime into several different ones. I did usually find it easier to just install the whole item to a new runtime, then delete it from the old one.

Link is to a tutorial at DAZ, on how to set up multiple runtimes. There are some great tips. For example, don't put your new runtimes in the Poser folder. Though it may seem natural to do that, since the "Downloads" runtime is there, Poser will run faster if you put them somewhere else. The main runtime and the Downloads runtime must stay where they are, but the others can be anywhere. Put them somewhere where the pathname will be as short as possible. It will save you a lot of scrolling and clicking. You'll kick yourself for not doing it sooner. :-)
