prompt: Your task is to convert the following English description into an ASCII tree format.
  
  argTypes is a core directory that organizes 2 subdirectories: convert and docgen.
  At the main level, 'convert' carries 4 diverse folders.
  Within directory hierarchy 'convert / __testfixtures__', '__testfixtures__' bundles 2 test-related directories.
  Within directory hierarchy 'convert → __testfixtures__ → proptypes', Inside 'proptypes', you'll find it is empty.
  Within directory hierarchy 'convert → __testfixtures__ → typescript', The 'typescript' container has been left empty.
  At level 2, in directory path 'convert / flow', Inside 'flow', you'll find it has no content.
  At level 2, in directory path 'convert > proptypes', Inside 'proptypes', you'll find it lacks any subdirectories.
  At level 2, in directory path 'convert > typescript', The 'typescript' collection is an empty container.
  At the main level, 'docgen' hosts 3 subdirectory elements: flow, typeScript, utils.
  In nested path 'docgen > flow', Inside 'flow', you'll find it holds no subdirectories at the moment.
  Within directory hierarchy 'docgen > typeScript', 'typeScript' is empty.
  In nested path 'docgen / utils', 'utils' lacks any subdirectories.
