I recommened the tut because some of the restrictions as to how you can and cannot re-order your files and folders apply to Studio.  Especially the parts about path lines inside many of the main files.  Its the path lines that point to other files, usually object files (*.obj) or textures.  Thats why you shouldn't mess with Geometry or Texture folders and their contents.  As bad as Poser's folder structure is I prefer to try to stick to it in case I ever do get Poser.
