prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  ws
   +--__snapshots__
   `--test
       `--__snapshots__
  ```
  
  Convert this description:
  
  _expected is a master directory that comprises 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the structure for you:
  
  At the top level, 'amd' has 1 folders: rollup_virtual.
  In nested path 'amd → rollup_virtual', Inside 'rollup_virtual', you'll find it is barren.
  Back to the top level.
  At the main level, 'cjs' has 1 contained folders: rollup_virtual.
  Within directory hierarchy 'cjs → rollup_virtual', Inside 'rollup_virtual', you'll find it has yet to be populated.
  At the main level, 'es' bundles 1 nested folders: rollup_virtual.
  At level 2, in directory path 'es / rollup_virtual', The 'rollup_virtual' folder is devoid of content.
  In the root directory, 'system' includes 1 nested folders: rollup_virtual.
  In nested path 'system > rollup_virtual', The 'rollup_virtual' data structure holds no subdirectories at the moment.
  Back to the top level.
