> 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.
