prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  [lang]
   +--@modal
   |   +--(.)feed
   |   `--(.)photos
   |       `--[id]
   +--feed
   `--photos
       `--[id]
  ```
  
  Convert this description:
  
  photos is a core directory that gathers 2 subdirectories: (.)[author] and [author].
  At the main level, '(.)[author]' retains 1 nested folders: [id].
  Within directory hierarchy '(.)[author] > [id]', Inside '[id]', you'll find it appears to be unused.
  At the main level, '[author]' shelters 1 contained folders: [id].
  At level 2, in directory path '[author] > [id]', The '[id]' container is devoid of content.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
