You can organize it how you want. I can't say this makes sense to me, but my runtimes probably wouldn't work for others either.

Multiple runtimes would be basically multiple library structures. Poser 13 has 4 to start with, Poser 13 content, Downloads, Included, and Purchases. You can create others as needed

each one of these is a different runtime in my library.

To make a new runtime, Create this file structure in Veiwer

Then follow the instructions in the first post to add it as a new runtime.

Of course, you don't have to use Magic and Effects as the runtime name. I just have an abundance of that so I gave it its own runtime.

I created this file structure in the props folder to further help me find things

As far as reorganizing later, it can be done but would be tedious.
