First off, I'll delete all the P4 (non PP) specific folders and references, then split the rest up manually. V2 characters, V2 poses, Clothes MATS Har MATS, and so on.

Which is EXACTLY how I have mine organized since I went to P5. I tried multiple runtimes but my aging gray matter got confused. :)
