prompt: Your task is to convert the following English description into an ASCII tree format.
  
  _expected is a top-level directory that collects 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the hierarchy for you:
  
  At the main level, 'amd' holds 1 nested folders: _virtual.
  In nested path 'amd / _virtual', Inside '_virtual', you'll find it is unpopulated.
  In the root directory, 'cjs' bundles 1 contained folders: _virtual.
  Within directory hierarchy 'cjs → _virtual', The '_virtual' storage space is empty.
  Back to the top level.
  At the main level, 'es' keeps 1 subfolders: _virtual.
  At level 2, in directory path 'es → _virtual', The '_virtual' section remains unused.
  Back to the top level.
  In the root directory, 'system' holds 1 nested folders: _virtual.
  Within directory hierarchy 'system → _virtual', Inside '_virtual', you'll find it is unpopulated.
  
  
  Format your response in this style:
  ```

   |   +--copy
   |   |   `--__tests__
