  Convert this description:
  
  type-params is a main directory that assembles 5 subdirectories. Notable ones include __snapshots__, consistent, empty-parameters-with-arrow-function among others.
  
  Let me break down the arrangement for you:
  
  At the top level, '__snapshots__' is unpopulated.
  At the top level, 'consistent' incorporates 1 directory entries: __snapshots__.
  Within directory hierarchy 'consistent → __snapshots__', '__snapshots__' remains unused.
  In the root directory, 'empty-parameters-with-arrow-function' stores 1 directories: __snapshots__.
  At level 2, in directory path 'empty-parameters-with-arrow-function / __snapshots__', Inside '__snapshots__', you'll find it has been left empty.
  Back to the top level.
  At the top level, 'print-width-120' contains 1 directory entries: __snapshots__.
  At level 2, in directory path 'print-width-120 / __snapshots__', '__snapshots__' has nothing inside.
  At the main level, 'trailing-comma' includes 1 subfolders: __snapshots__.
  At level 2, in directory path 'trailing-comma / __snapshots__', The '__snapshots__' folder contains no subdirectories.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
