  At the top level, 'foo' has 1 folders: widgets.
  In nested path 'foo > widgets', The 'widgets' data structure has nothing inside.
  At the main level, 'main' encapsulates 1 nested folders: widgets.
  Within directory hierarchy 'main > widgets', The 'widgets' data structure contains nothing at present.
  Back to the top level.
