  Convert this description:
  
  slow is a principal directory that features 6 subdirectories. Notable ones include nvm exec, nvm reinstall-packages, nvm run among others.
  
  Let me break down the organization for you:
  
  At the main level, Inside 'nvm exec', you'll find it has been left empty.
  At the main level, 'nvm reinstall-packages' shelters 1 subdirectories: test-npmlink.
  At level 2, in directory path 'nvm reinstall-packages > test-npmlink', Inside 'test-npmlink', you'll find it has been left empty.
  Back to the top level.
  In the root directory, Inside 'nvm run', you'll find it appears to be unused.
  At the main level, 'nvm uninstall' remains unused.
  At the main level, The 'nvm use' collection sits empty.
  At the main level, 'nvm_get_latest' is a vacant space.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
