May I add a caution that you should consider keeping Poser library *mostly* as 'External', just link in 'Usual Suspects', plus what you need for current project...

IMHO, Poser does not appreciate having its data-base(s) congested, be it by a zillion library items or several dozen FBX sub-rigs...
( 'Parent' latter to their 'master' sub-rig ASAP !!!)

Having a sprawling archive of '3D Stuff' that began before P_3 and is now several Terabytes of file-formats ranging from 3DS via SFM to XPS, I've learned that Windows, for all its faults and petty exasperations, does have a fair search-engine...
