Wrong path to the home page

Hi everybody,
I’ve to move a wordpress website into a subfolder of my server.
The site main address is http://www.varvaria-breberium.bribir.com and now the wordpress site is in the following folder: http://www.varvaria-breberium-bribir.com/wordpress

Where can I set the right path to the folder?
I’ve tried to modify index.php, .htaccess and the Reading setting in wordpress but it doesn’t work.
Thanks
