I added a subfolder to my Poser 8 runtime.  I saved a morphed character to the subfolder.  I then went to Cararra and to my surprise, the folder was not in the content box for my Poser 8 runtime.  So, I went to Windows 7 and checked the file structure for my Poser 8 runtime.  Sure enough, the subfolder was not there.  I went back to Poser - it still lists the missing subfolder in the Poser 8 runtime and gives me access to the character's CR2. 

Where oh where could my little file be?

I tried using Poser 8's native library.  I then tried another experiment with Dimension 3D's library script.  Both had the same result. Poser says it created a file subfolder and continues to access it.  The file subfolder cannot be found in Windows 7 or Cararra.
