  empty dir --out-dir is a primary directory that groups 2 subdirectories: in-files and out-files.
  At the main level, 'in-files' encapsulates 1 contained folders: src.
  At level 2, in directory path 'in-files → src', Inside 'src', you'll find it contains nothing at present.
  At the top level, 'out-files' bundles 1 subdirectories: src.
  At level 2, in directory path 'out-files → src', 'src' is a vacant space.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
