The only folders you should organize are in the Libraries folders (but not !DAZ and other folders that don't equate to things in the library because the morph injection folders have to be in their default installation). It's really a manual effort and Explorer gets the job done since it's just a matter of creating directory folders for the categories that you want to organize around and moving the content that belongs in each. It's a bear of a task up front, but becomes easier once you've set up your own organization system.
