Serving static files
Files and folders that are uploaded are not automatically available to the web application clients through HTTP requests. These will need to be associated with one or more site url(s) in order to be available. See site urls and static files on how to publish an entire folder tree to be accessible through HTTP requests.
Accessing site files content
Sometimes a web application needs to generate content server side through server side plugins or using batch mode . In both cases the web application will use WPBContentProvider interface in order to fetch content, including site files content.
In other words, a file content uploaded under site files will be accessible from controllers by using WPBContentProvider interface.
