Phpmyadmin problem

hi all..

I have a question about the setup of phpmyadmin. I'm running phpmyadmin on windows, powered by xampp.
Now i need to change the settings; ./phpmyadmin/scripts/setup.php.

I changed the settings and saved the file. It need to be saved in './config/config.inc.php' on the webserver.
But the dir './config' dont exist, and i don't know were the file 'config.inc.php' is saved.

// Source from ./phpmyadmin/scripts/setup.php.
$fail_dir = FALSE;
$fail_dir = $fail_dir || !is_dir('./config/');
$fail_dir = $fail_dir || !is_writable('./config/');
$fail_dir = $fail_dir || (file_exists('./config/config.inc.php') && !is_writable('./config/config.inc.php'));
$config = @fopen('./config/config.inc.php', 'a');
$fail_dir = $fail_dir || ($config === FALSE);
@fclose($config);

Can someone help me out, i need to know were the 'config.inc.php' is saved from the setup.

Thanks in advance
