I'm doing what is normal to do with daz products. Its always been this way, and statements otherwise, are uninformed. The vast vast vast majority of products can be rearranged. (In fact this is the only reason I don't buy Daz's encrypted products.)

Donnena, Daz has no logic that is discernible when it comes to how products are placed in libraries. Every single product goes to a magical location thunk up by the product's creator. If you'd used it as long as I have and bought as much as I had, you'd also notice that artists are rarely consistent within their own product lines.

I learned early on that my product library is unusable if its not properly curated, so I've been sorting all installs for a healthy 10 years now. I also test installs, since they are often not tested. (I notice actual faults about 2-5% of the time...)

I never rearrange data or runtime (other than the Poser Library).. I don't really care what happens out of sight of my library, but I have noticed that its a REAL MESS.
