  Convert this description:
  
  node_modules is a master directory that features 3 subdirectories: abc, def and xyz.
  In the root directory, 'abc' contains 1 nested folders: node_modules.
  At level 2, in directory path 'abc → node_modules', 'node_modules' has 1 packages: xyz.
  In nested path 'abc / node_modules / xyz', 'xyz' is currently empty.
  At the main level, 'def' features 1 contained folders: node_modules.
  In nested path 'def → node_modules', 'node_modules' keeps 1 packages: xyz.
  In nested path 'def / node_modules / xyz', Inside 'xyz', you'll find it is an empty container.
  At the main level, The 'xyz' data structure is a vacant space.
