One of the things I really like about P5 is the ability to arrange Libraries any way I want just by using normal Windows Explorer drag n' drop copy methods. I totally rearranged my P5 Library folder structure after copying in all my P4 Runtime files (being careful not to overwrite any stuff unique to P5). Now I have my 12 Gig Runtime entirely in P5 arranged to my liking, and don't have to keep P4 on my system since I didn't link the P4 Runtime to P5. Also, I don't have to face the decision as to which version of Poser Runtime (P4 or P5) to add new items to in the future - they all go in P5. This all made using PBoost and CorrectReference unnecessary. P5 recognizes everything I copied over from P4. Best of all, all of my MAT files are categorized nicely and I don't have the old P4 problem of not being able to read the MAT file headers that happened with an overloaded P4 Pose Library (i.e., the dropdown list becoming to narror to show the full folder names).
