At first I was excited by subfolders but then they lost thier alure. Back with P4 I had different runtimes and tricked Poser by naming the "1-Rubtimes", "2_Runtimes", etc. and lopping off the "prefix" of the one I wanted to use for my work in Windows Explorer. I never did get them properly organized so I think I will reinstall everything fresh into new runtimes for P6... I just have not figured out the best schema yet. I use P5 mainly for clothroom and sometimes Face Room and Materials MATS and occasionally node stuff... but for speed in my comercial stuff and personal stuff I most often use P$... I postwork the heck out of everything anyway.
