This my actual libraries (sorry it in in Das Studio).

@All - I think now I understand there has been some missunderstanding. My file setup is only for  the vendor to distribute their products. It is not for the end user (purchaser).

There really can't be one standard for all as everyone agrees that we like to organise our files differently as our workflows and think are different.

However with the vendor distributing their product in one standard then the end user can easily find andthe products and relocate them to their library subfolder of their choice.
