Protecting Uploads from non-subscribers

Hi,

I have been looking high and low for an answer to this. I have a WP site that has only subscriber content. All the files I upload though, I notice are available to be downloaded by anyone. So far I have been able to prevent content (eg. Posts) from being displayed to unauthenticated users but if a person types in a specific URL they are able to download files within the wp-content/uploads. I am hosting this site on Godaddy so I am sure there will be limitations as to how I configure folder permissions if that is the route. I am assume this is a common issue for people that have subscriber only content (eg. files, media, etc…).

Plugins correctly installed: Remove Dashboard Access, User Role Editor, Widget Logic, WP-Members.

Any help would be greatly appreciated. Thanks
