Quote - To use another post of mine from that 4 year old thread I mentioned before, I suggested something like this:

Quote -     Libraries
        Regular library folders
            Merchant
                ProductName
                    product files
                    AddOn folders*

    Pose
        MATs
            DAZ
                MorphingFantasyDress
                    KeithsAmazingMFD

At the time I suggested this, someone pointed out that they'd hate the structure the way I did it, and that's fair enough because that sort of thing was personal preference.

I would hate it too! In the libraries I don't want my top level folder to be cluttered with a million merchant names and not have any clue what's in them or what figure they are for. That's why I would structure it by figures first. IE:

    Libraries
        Regular library folders
            Figure Vendor (IE: DAZ or SM or 3D Zone etcetra)
                     Figure (IE: Victoria or Jessi or Toon Sam etcetra)
THEN I would go      Merchant
                                         ProductName
                                                    product files
                                                                    AddOn folders*

Yeah my tree structures are deeper but the top levels are very clean.
