Wow! Just Wow! That is a hell lot of work, you put in there.

Okay, for this to be the way you run this, you had to come up with this kind of structure on some point in time in which the runtimes were significantly smaller, right? Otherwise to put all this stuff in the place where it belongs, would be a very time consuming task, right?
I assume your runtimes have grown over time, item for item.
A few years ago, I made a similar approach, putting all the figures into seperate runtimes, including poses, clothing and such. But I desided to merge those runtimes into one, because I fund it rather difficult to deside on each item where it should go.
There are several items who are meant for two figures, like poses for M3 and V3, or hair that can be used for many figures. Some of the very old items came with textures who wasn't properly named, so I had to search for them in several runtimes manually.
But I think your way of managing your runtimes is interesting.
I'm curious, what product do you use to create this database?
I know there are many scribts and tools for Poser out there.
I don't use most of them because for my workflow I don't really need them, but this looks very helpful.
