prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  app
   +--(bar)
   |   `--bar
   `--(foo)
       `--foo
  ```
  
  Convert this description:
  
  preserve-modules-filename-pattern is a master directory that maintains 2 subdirectories: _expected and src.
  At the top level, '_expected' keeps 4 some directories.
  In nested path '_expected → amd', 'amd' encompasses 1 contained folders: nested.
  Within directory hierarchy '_expected > amd > nested', The 'nested' data structure is currently empty.
  At level 2, in directory path '_expected → cjs', 'cjs' encapsulates 1 folders: nested.
  At level 3, in directory path '_expected → cjs → nested', 'nested' is devoid of content.
  In nested path '_expected / es', 'es' organizes 1 nested folders: nested.
  At level 3, in directory path '_expected → es → nested', The 'nested' collection lacks any subdirectories.
  In nested path '_expected → system', 'system' incorporates 1 directories: nested.
  Within directory hierarchy '_expected > system > nested', The 'nested' folder is blank.
  In the root directory, The 'src' section holds 1 folders for code organization.
  In nested path 'src / nested', Inside 'nested', you'll find it lacks any subdirectories.
