Here's a sample of how the directories are laid out. Note that there should be no spaces for directories. Every directory must have an info.txt file associated with the directory. The info.txt file can contain notes within the directory.

• The model directory (modl)
  • root directory of course note
    • directory 1
    • directory 2
      • subdirectory 1
      • subdirectory 2
    • directory 2
      • subdirectory 1
      • subdirectory 2
      • subdirectory 3
    • directory 3
      • subdirectory 1
        • subdirectory 1 of subdirectory
        • subdirectory 2 of subdirectory
      • subdirectory 2
    • directory 2
      • subdirectory 1
      • subdirectory 2
      • subdirectory 3
      • subdirectory 4
      • subdirectory 5
