   Actions
        Display the contents of the folder
        
   Notes:
    1. If the folderuuid is absent then the contents of the root folder are returned.
    2. The 'seen' field indicates if the user has viewed this resource before
    3. The versions field list only shows if 'hasversions' is set to 1
    4. The updatedat field will change if anything gets updated e.g. description, file. So if versions
        are not enabled or are notmandatory and turned off for a file updated, then in order to know
          whether the file has been updated and needs to be downloaded again, compare the processedat fields. This field
        only changes when the file gets replaced.
