How to attach/deattach a Express database to a fullblown SQL Server 2005

Hi. I would like to if its possible to take a Express ".mdf" file and attach it to a full blown SQL Server 2005?, to "attach" it to a real SQL Server 2005?. And how do i do this?. or do i have to do it since there is a "DataDirectory" directive that manage this for me in the connectionstring?, im a little newbie about this :)
