Can anybody help to solve this error? Thank you.

<?php /// Moodle Configuration File

unset($CFG);

$CFG->dbtype = 'mysql';
$CFG->dbhost = 'localhost';
$CFG->dbname = 'moodle';
$CFG->dbuser = 'xxx';

Warning: main(D:\xampp\htdocs\moodle/lib/setup.php): failed to open stream: No such file or directory in /Users/student/ting/Sites/xampp/moodle/config.php on line 22

Fatal error: main(): Failed opening required 'D:\xampp\htdocs\moodle/lib/setup.php' (include_path='.:/Applications/xampp/xamppfiles/lib/php') in /Users/student/ting/Sites/xampp/moodle/config.php on line 22

Are you sure these physical paths are correct?

$CFG->dirroot = 'D:\xampp\htdocs\moodle';
$CFG->dataroot = 'D:\xampp\moodledata';

Shall we just stick to ONE THREAD?
