prompt: Your task is to convert the following English description into an ASCII tree format.
  
  api is a parent directory that encompasses 3 subdirectories: file, internal and tasks.
  At the main level, The 'file' directory is devoid of content.
  At the main level, 'internal' possesses 5 various subdirectory elements.
  In nested path 'internal / attributes', 'attributes' bundles 1 subfolders: immutable.
  In nested path 'internal / attributes / immutable', Inside 'immutable', you'll find it remains unused.
  Within directory hierarchy 'internal → catalog', 'catalog' hosts 1 directories: problems.
  Within directory hierarchy 'internal → catalog → problems', 'problems' holds no subdirectories at the moment.
  At level 2, in directory path 'internal > file', 'file' possesses 1 subdirectories: copy.
  At level 3, in directory path 'internal → file → copy', 'copy' has no content.
  Within directory hierarchy 'internal → project', 'project' contains 1 child directories: taskfactory.
  Within directory hierarchy 'internal > project > taskfactory', 'taskfactory' sits empty.
  In nested path 'internal / tasks', 'tasks' comprises 1 directories: properties.
  Within directory hierarchy 'internal → tasks → properties', 'properties' incorporates 1 subdirectory elements: bean.
  At level 4, in directory path 'internal → tasks → properties → bean', Inside 'bean', you'll find it has no folders inside.
  Back to the top level.
  At the main level, 'tasks' carries 1 subdirectories: bundling.
  At level 2, in directory path 'tasks > bundling', Inside 'bundling', you'll find it is an empty container.
  Back to the top level.
