Diggit Drupalextras

I am sorry but I couldnt find an answer to this question when I searched the forum.
I wish to know if it is possible to install Drupal in a folder on my server and make it work as the main site. Like, I install it in : www.mysite.com/drupal but I want that when my visitor clicks on www.mysite.com, it should open the drupal site without showing the folder 'drupal' in the links. This is possible in Wordpress (read this: http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory).
Looking forward to a response.
