  Convert this description:
  
  fingerprint is a fundamental directory that features 2 subdirectories: classpath and impl.
  In the root directory, 'classpath' organizes 1 subdirectories: impl.
  At level 2, in directory path 'classpath → impl', Inside 'impl', you'll find it is a vacant space.
  Back to the top level.
  At the top level, 'impl' holds no subdirectories at the moment.
