small mistake about 'get_dir_file_info'

For example:
if 'test.txt' is contained in '\public' and his sub folder '\public\uploads', the result is only:
[Test.txt] => Array
(
[Name] => test.txt
[Server_path] => ......\public_\uploads\test.txt

and will not be counted twice (once in '\public' and two again in '\public\uploads')
