While read access is the only permission available on most websites today, read access for directories allows for a direct listing. This directory listing shows the user only files which they are given permission to read. Though many users might have directory read access, the view can be controlled and made more efficient with read-access controls. Write access allows a user to upload files to WFS 3.0. Directory write access allows only those with that permission to write to that directory.
Delete access enables users to completely remove a file or directory.
