The public Files page allows anyone (not just club members) to see any files that have been marked as public. By default, NO files are marked public. As long as the club is not using a trial subscription, files can only be marked public from the main File storage page, by using the black arrows to reveal sub-folders and files.
For more on marking files public or private, please see our FAQ page at:
