We all have different ways of doing things, some people have one runtime and it works for them, but my system is set up according to how I work. I have some major runtimes such as Female, Male, Shaders, Scripts, Clothing, Footwear,  Hair. I have a very large collection been working with this stuff for more 15 years. Everything else I use is based on the genre it falls in. Example Theme-Apocalyptic-Cyber-DieselPunk-Dystopian-Military -SciFi-Wasteland - has everything that falls within any of these genre because this is how my scenes are created. Theme-Scary has anything that is scary to me, vampires, horror, halloween, ghosts, etc.  Theme-Fantasy has all fantasy stuff, Theme Crime has all crime related stuff, etc. These themes have both the Poser and the Daz files. I use lots of poser stuff in my designs but I simply apply Daz shaders as needed. Some of these freebies we get have no structure they are simple in a zip file with no runtimes everything in one section. A bit frustrating, but still usable. The stuff I post in my gallery is simply me testing out the files to see if they work the way I want, once the testing is done I simply upload to my gallery.
