  app-dir-export is a primary directory that holds 2 subdirectories: app and test.
  In the root directory, 'app' shelters 4 subdirectories that organize the source code.
  Within directory hierarchy 'app → another', 'another' bundles 1 nested folders: [slug].
  Within directory hierarchy 'app → another → [slug]', The '[slug]' storage space sits empty.
  Within directory hierarchy 'app → api', 'api' organizes 2 child directories: json, txt.
  In nested path 'app > api > json', The 'json' compartment is barren.
  In nested path 'app → api → txt', Inside 'txt', you'll find it sits empty.
  At level 2, in directory path 'app > client', 'client' sits empty.
  At level 2, in directory path 'app → image-import', The 'image-import' section has been left empty.
  In the root directory, 'test' is vacant.
