  Convert this description:
  
  classes is a root directory that groups 3 subdirectories: __snapshots__, keyword-property and top-level-super.
  At the main level, '__snapshots__' has nothing inside.
  In the root directory, 'keyword-property' carries 1 folders: __snapshots__.
  In nested path 'keyword-property → __snapshots__', Inside '__snapshots__', you'll find it remains unused.
  Back to the top level.
  At the top level, 'top-level-super' contains 1 subdirectory elements: __snapshots__.
  At level 2, in directory path 'top-level-super > __snapshots__', The '__snapshots__' compartment has yet to be populated.
