prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  es_declare_module
   +--__snapshots__
   `--flow-typed
       `--__snapshots__
  ```
  
  Convert this description:
  
  _expected is a fundamental directory that organizes 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the construction for you:
  
  At the top level, 'amd' incorporates 1 subdirectories: _virtual.
  In nested path 'amd > _virtual', The '_virtual' data structure has nothing inside.
  At the main level, 'cjs' has 1 child directories: _virtual.
  Within directory hierarchy 'cjs → _virtual', Inside '_virtual', you'll find it has no folders inside.
  At the main level, 'es' has 1 contained folders: _virtual.
  At level 2, in directory path 'es → _virtual', Inside '_virtual', you'll find it lacks any subdirectories.
  At the main level, 'system' bundles 1 folders: _virtual.
  Within directory hierarchy 'system > _virtual', Inside '_virtual', you'll find it appears to be unused.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
