  watch is a fundamental directory that contains 2 subdirectories: registry and vfs.
  In the root directory, 'registry' keeps 1 directory entries: impl.
  In nested path 'registry > impl', 'impl' is vacant.
  At the main level, 'vfs' hosts 1 nested folders: impl.
  In nested path 'vfs / impl', 'impl' is blank.
  Back to the top level.
