  At level 2, in directory path 'app > classic', The 'classic' folder contains nothing at present.
  In nested path 'app > module', 'module' has no folders inside.
  At level 2, in directory path 'app > string', Inside 'string', you'll find it sits empty.
  In the root directory, Inside 'public', you'll find it holds no subdirectories at the moment.
