Files go in poser runtime, libraries then from there it's about what it is. obj goes in geometries cr2 files go in characters or figures pp2 files go in prop png are the picture thumbs you see pz2 files are poses fc2 are face files hr2 are hair files cm2 are camera files lt2 are lights I'm not sure I got em all but those are the basics I know fairly well. When I first started poser someone gave me a list similar to this and it helped me start to figure it out. So I thought I would return the same. I hope it helps you as much as it helped me :) Oh yes and the read me's really really don't lose those if you can help it lol. Retitle them if need be and make sure after each install you put em where they belong or you'll end up with tons of readme's all with different spelling variations of ReadMe. Like Tim said ;) Welcome to poser addiction!
