The Poser Library is compatible with this approach certainly... i.e. it will show a hair prop or prop in the character section of the library, if you place these in the sme directory under one of the sections.

However the handy utility to organise this, that I use, is Windows Explorer / Finder ;-)

I don't know if SharerWorks Library Manager will achieve this perhaps, from within Poser... Estherau (or anyone else using this) might be able to advise?

Hmmm... seriously tempted by that myself, now it's on sale again.
