The Download Protect plugin for WP-Members allows you to load files such as documents, PDFs, zip files, etc to a protected directory requiring the user to be logged in to access.
Files are uploaded to a separate folder within the main WP file upload folder structure and that folder is restricted from direct access. All files are served through a script-based process that prevents them from being accessed directly. If a user is not logged in, they can be directed to an error page that requires them to log in.
Even if the direct link to the file within the file structure were known, the file cannot be accessed directly.
There is a basic demo on the WP-Members Demo Site.
IMPORTANT: This extension is for blocking access to file downloads. It is not for streaming media. It can be used to block access to media files that are intended to be downloaded, but if your intention is to block access to media files that you deliver through a streaming player, this will not work for that purpose.
