/*

  Watch out, os.IsExist(err) != !os.IsNotExist(err)

  They are error checkers, so use them only when err != nil, and you want to handle
  specific errors in a different way!

  Their main purpose is to wrap around OS error messages for you, so you don't have to test
  for Windows/Unix/Mobile/other OS error messages for "file exists/directory exists" and
  "file does not exist/directory does not exist"
