> The File.mkdir() API requires the parent directory have to exist, otherwise a
> failure will occur. To ensure the safety of file creation, the File.mkdirs()
> is preferred as it will create the parent directory as well if needed. This
> is important as if it fail, program may potentially crash. Besides, mkdirs()
> causes no extra overhead.
