Everything I've bought has its own folder. For example, the Ali hair. In this folder are all the Ali hair and only one runtime folder. I put this folder in the library. The only thing that is installed in Poser 11 or Poser 13 are the figures.

Unfortunately, the Poser 13 folder doesn't work in the body morphs.

So I've now removed it from the library and put the Poser 11 folder in the library instead. It worked wonderfully.

Everything else isn't installed in Poser 13. It takes up too much space in Poser and at some point, I think, it will be too much anyway. So I put each folder separately in the library. What I always need. What I don't need, I remove from the library.

I have no idea about anything else technical. I only work with Poser, create figures or backgrounds. I don't do anything else with it.
