Proper folder structure and pointer routing

Hello,

I am not sure how to phrase this question. I am using a hosting service that has domain pointers. However for my site to be live I have to set the pointer to /examplefolder/index.php . when I do this everything works fine, but I have no access to wp-admin.php because it is not found. How can I access the dashboard while the site is LIVE so I can update blogs and SEO? With other hosts I have been able to do this no problem. Should I unpack my wordpress folder into the main directory?

Thanks
