prompt: Your task is to convert the following English description into an ASCII tree format.
  
  fixtures is a core directory that features 5 subdirectories. Notable ones include babelrc, browserify, internal-modules among others.
  
  Let me break down the formation for you:
  
  In the root directory, 'babelrc' lacks any subdirectories.
  At the main level, The 'browserify' storage space is a vacant space.
  At the top level, The 'internal-modules' directory is devoid of content.
  At the top level, The 'mjs-babelrc' collection has been left empty.
  At the main level, 'source-map' bundles 1 subfolders: foo.
  At level 2, in directory path 'source-map / foo', The 'foo' folder remains unused.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  gradle
   +--api
   +--internal
   `--util
       `--internal
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
