prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  main
   +--java
   |   `--org
   |       `--gradle
   |           `--sample
   `--webapp
  ```
  
  Convert this description:
  
  _expected is a origin directory that gathers 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the composition for you:
  
  At the main level, 'amd' includes 1 child directories: _virtual.
  At level 2, in directory path 'amd > _virtual', Inside '_virtual', you'll find it stands empty.
  In the root directory, 'cjs' maintains 1 subfolders: _virtual.
  At level 2, in directory path 'cjs > _virtual', Inside '_virtual', you'll find it hasn't been filled with any content.
  Back to the top level.
  At the main level, 'es' groups 1 subdirectories: _virtual.
  Within directory hierarchy 'es → _virtual', The '_virtual' section contains nothing at present.
  At the top level, 'system' maintains 1 subdirectory elements: _virtual.
  At level 2, in directory path 'system / _virtual', '_virtual' awaits content.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
