   |   `--_images
   +--gis
   |   `--install
   `--postgres
  ```
  
  Convert this description:
  
  test is a head directory that consolidates 3 subdirectories: fixtures, helpers and types.
  In the root directory, 'fixtures' stands empty.
  At the top level, The 'helpers' folder awaits content.
  At the top level, 'types' hosts 2 folders: create-test-server, slow-stream.
  In nested path 'types → create-test-server', 'create-test-server' holds no subdirectories at the moment.
  At level 2, in directory path 'types / slow-stream', 'slow-stream' is currently empty.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
