Poser P4, PP, P5 reads every library folder when launching (in the current runtime only in the case of P5). Every file, every sub-directory. And yes, it does read in alphabetic order. Whenever Poser can't find a texture in the location specified in the items .cr2/.pp2/.pz2/ect file, then it again searches every folder in alpha order in Runtime. And yes, I did mean to say "every". It searches .dll's, the entire Python folder, etc, so it'll be reading for quite a while before it even gets to the Textures folder! This is why using CRPro to correct texture - and other - links can make such a huge improvement to Poser operation. Oh, and BTW Poser doesn't close any of the folders it opens to search for textures!!! Except for the final one iff it finds the texture somewhere. In Win9x this sloppiness is ignored by the OS, but the Win2k/XP Windows records and holds open - ie. locked - each of those folders until Poser.exe is closed. (I understand why this bug wasn't addressed in Poser 4 and PP, but P5 and certainly the P5SR's were released well after Win2K became prevalent.) I certainly agree with Veritas777's method of 1 geometry folder and separate libraries for the reasons that he gives, and PBooost let's you do this easily. Check out PoserPros P5 Tips and Tricks forum for a compendium of ways to speed up Poser. Some apply to P4 and PP too.
