Looking for some help or something easy or already built. I found a database free online that will work for me to save technical manuals and other documents. What I would like is a front end that shows a tree structure that will allow a user to click on the structure and open up the files and read or download. The back end, which I can do is linking this to the main page that allows someone to create a technical articles or upload one. Anyone help out or know the best way? Thanks.
