prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  tests
   +--client_certs
   |   `--password_protected
   +--fixtures
   |   +--session_data
   |   |   +--new
   |   |   `--old
   |   `--xmldata
   |       +--invalid
   |       +--valid
   |       `--xhtml
   `--utils
       `--matching
  ```
  
  Convert this description:
  
  _expected is a central directory that includes 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the formation for you:
  
  At the main level, 'amd' houses 1 contained folders: assets.
  In nested path 'amd > assets', Inside 'assets', you'll find it is barren.
  At the main level, 'cjs' houses 1 subdirectories: assets.
  In nested path 'cjs / assets', The 'assets' directory is currently empty.
  At the top level, 'es' contains 1 folders: assets.
  Within directory hierarchy 'es → assets', The 'assets' folder is devoid of content.
  At the main level, 'system' incorporates 1 directories: assets.
  In nested path 'system > assets', Inside 'assets', you'll find it hasn't been filled with any content.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
