I am loath to archive the stuff in my runtime directory. PZ3 files and end products like images, I'll archive (twice). I prefer to decrease the number of directories within a library and increase the number of items in a directory by type. This is a function of how much stuff is available in any given category and how do I want to access it. The criterion is each case is visual - how long is the list? There are only eight categories of libraries and that is the shortest span in all of Poser. If each category of library (poses, characters, etc) could be split, the number of directories within a library could be reduced to a more easily managed number. Nesting might be a problem with the libraries as they are accessed directly from the face of Poser. The other directories are not.
