D-Man (Download Manager)
A PHP4/MySQL download manager that provides a simple and secure way to manage who has access to download your files and which ones. Your download files are kept in a location inaccessible from the web, and session tracking, optionally encrypted passwords, and a variety of user/file group systems ensure only authorized access. You may allow users to create their own accounts and optionally require admin approval. A Credits system can also be used. Email authorized users of specific download updates (such as for programs), or carry forward authorizations from one download to another. Includes many administrative tools and optional registration/license generator and auto payment processor (PayPal) plugins.
