Best Dreamweaver Extension for file upload/download

I am a teacher and want to create a site to have my materials available for download to students.  I have experience with dreamweaver and have built a few sites.  Currently the class I am taking over uses Google docs and it is clunky garbage.  I can create a login area where my cooperating teacher (We teach different aspects of the course together) can upload her material.  Then set up pages for students to download the documents if they need.  I am sure there is a great extension out there fr this without me having to hand code it in php/mysql.  Thanks for the feedback.
