Find a workflow of using Daz Studio that make sense to me

I still don't like using Daz Studio 4 mostly because of the fact that it doesn't intergrate with my pre-DazStudio4 content well.  So eventually I continue using Daz Studio 3 Pro 3.1.2.24 to create the scenes, set contents and so on.  And if I really needed, I can open that scene on Daz Studio 4 anyway.  That works nice in my case.

Daz Studio 4: how to make all your files successfully open anywhere

Once again I have Daz Studio (this time it is Daz Studio 4 Pro 64 bit) installed on a new machine, and once again the file did NOT open properly, claiming that some files are missing.

I already tried to mimic the file structure to match perfectly even down to physical location and still didn't work.  Finally I found out, by reading the log file (which is in C:\Users\xxxx\AppData\Roaming\DAZ 3D\Studio4\log.txt) that a whole directory tree "C:\Users\xxxx\Documents\DAZ 3D\Studio\My Library\data\4_0" is missing, and so I copied the whole directory and now it's working relatively OK.

Now my next step is to set up SyncToy to make sure that the following 2 directories are perfectly match among my installations:

C:\Users\xxxx\Documents\DAZ 3D\Studio\My Library\data
C:\Users\xxxx\Documents\DAZ 3D\Studio3\content
