First...THANK YOU!!!

So, there was a huge amount of data to unpack there but I now have what I was looking for and new questions.

Hovering over "My Library" I saw  ...user/Marc/Documents/DAZ 3D/Studio/My Library
  Navigating to .../Documents/DAZ 3D/Studio", I saw /My Daz Connect Library/data/cloud"
  But that directory was empty

Under "My Library" is a link: "My DAZ 3D Library" and hovering over showed "...user/Marc/Documents/My DAZ 3D Library"
  But, navigating to "...user/Marc/Documents", I only see the DAZ 3D" directory mentioned above.  No "My DAZ 3D Library" as expected.

Finally, under "My Library" and "My DAZ 3D Library" is a Second "My DAZ 3D Library"
   Hovering over that shows the location:   C:/DAZ 3D/Applications/Data/DAZ 3D/My DAZ 3D Library

Now, this is a huge amount of data sitting in C: root!  And DAZ does not seem to allow for content management on install.
   So, I looked into moving the data, but the "move" tools in Content Directory Manager only moves up or down in the existing locations.  So, how do I move my data to a new directory on my E Drive?  Do I have to create a new location in the app and then move the data?  
   And, does the data automatically move when I do that?
