It sure looks like the dreaded too-many-folders syndrome to me, too. First question is... Do you need that many installed items? Even with a library manager, do you really need to access all of them all of the time? If you do, get better organized (with or without a pre-set system); if you don't, just keep the ones you are currently working with and the basic files needed for Poser, and tuck the others elsewhere on your drive.
