How do I list out all the posts under a custom post type?

Hi there,

I was wondering how I would get to list out all the posts in a custom post type i created using custompress? While in the editor I can click on ‘view’ and I can see the individual page using the template I edited that custompress helped me create but I want to see the a page with the listing of all the posts under the custom posts that I created. Is that just the archive.php page? I need to be able to layout all the listing in a custom way using custom fields too.
