why 2 runtime folders? is this normal

I've being buying some stuff from renderosity as of late, and installing things manually and I think I screwed something up.
I now have 2 runtime folders:
C:\Users\Public\Documents\My DAZ 3D Library\Runtime
and
C:\Users\Public\Documents\My DAZ 3D Library\content\Runtime
I'm not sure when or how this happend. It wasn't just a missed drag and drop or copy, because I have more than a few things installed in this second path, though the majority of my stuff is installed in the first path above. And everything as far as I can tell works.
Should I just reinstall the stuff that is in ...content\runtime? Does it make a difference?
is there a reason for having 2 runtime folders?
This is going to keep me from sleeping now.

It is a problem to have a runtime folder nested inside a "content" folder. You should not have that "content" folder.
You can merge the contents of C:\Users\Public\Documents\My DAZ 3D Library\content\Runtime with C:\Users\Public\Documents\My DAZ 3D Library\Runtime. When you install manually next time, take the contents of "content" and copy it to C:\Users\Public\Documents\My DAZ 3D Library. Do not copy the "content" folder itself. You should never create nested runtime folders.
I also have a data, materials, and people folder in that same content folder, with a few things in each. I'm guessing that is a problem as well?
Got it, thank you.
Yes, thanks again for your quick advice. It was an easy fix and everything is where it should ne now.
