changing the URL folder

hi

Please can somebody tell me how I get WordPress to read my installation from a different folder instead of from the root?

at the moment my domain looks like http://wimbornevideoclub.co.uk/vcbut I want to drop the vc when it is being searched for. I have already tried several methods including changing the site URL and WP URL in the backend of WordPress, changing the WP_config.php, function.php, none of which have worked and I’m running out of options!

I have only just started using WordPress as I have been using Joomla! for the last 5 years. I don’t really want to put the WordPress installation in the root as I might want to install other instances of WordPress on the same server.

I am using WordPress 3.8 and from what I can see from other people’s advice on the Internet and YouTube one of these methods I have tried should have worked

Thanks in advance
