This plugin allows you to upload and download documents that are stored outside of your web document root for security purposes.
This is great for people using plugins like Registered Only (and here) that secure your WordPress blog (Posts, Pages, etc). The problem with these plugins is that your loose files arenâ€™t protected - only the contents of your WordPress database. So, any images or other documents youâ€™ve uploaded are easily accessible to those who arenâ€™t authenticated via a plugin like Registered Only. This plugin aims to solve this problem.
