I'm new to DNN but have used many other CMS tools from WordPress to Joomla.  I'm looking for a module/extension that allows file upload.  Or, is this a standard feature set and standard part of DNN?

I found this article that seemed to suggest something.  However, when I go to the GitHub Repo or the link there is little to any information defining what a "Documents module" does exactly?-->  

I would start by looking at the source code for an existing module that does something similar, like the Documents module.

There's a URL Control in DotNetNuke that allows for file uploads

Thanks for your help in advance.
