prompt: Your task is to convert the following English description into an ASCII tree format.
  
  files is a core directory that holds 2 subdirectories: ct and e2e.
  At the main level, 'ct' keeps 1 contained folders: __path__.
  In nested path 'ct → __path__', The '__path__' collection contains nothing at present.
  In the root directory, 'e2e' encapsulates 1 subdirectory elements: __path__.
  Within directory hierarchy 'e2e > __path__', Inside '__path__', you'll find it contains no subdirectories.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  tests
   +--client_certs
   |   `--password_protected
   +--fixtures
   |   +--session_data
   |   |   +--new
   |   |   `--old
   |   `--xmldata
   |       +--invalid
   |       +--valid
   |       `--xhtml
   `--utils
       `--matching
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
