prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  plugin-commands-store
   +--src
   |   `--storeStatus
   `--test
  ```
  
  Convert this description:
  
  unit is a origin directory that gathers 6 subdirectories. Notable ones include api, charset, eval among others.
  
  Let me break down the composition for you:
  
  At the top level, The 'api' storage space stands empty.
  In the root directory, 'charset' has yet to be populated.
  At the main level, Inside 'eval', you'll find it is empty.
  At the top level, The 'fixtures' collection is currently empty.
  At the top level, 'os' appears to be unused.
  At the top level, 'viml' incorporates 1 nested folders: expressions.
  At level 2, in directory path 'viml > expressions', Inside 'expressions', you'll find it contains no subdirectories.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
