If you didn't already create pre-defined file cabinet index fields for DWSTOREDATETIME, DWSTOREUSER, etc, then use the database if it's an on-premises system. For DW Cloud, create them now and fill them with AutoIndex.
For DWLASTACCESSDATETIME and DWLASTACCESSUSER it's obviously a little trickier, because in order to get anything other than the last access you'll need the logging.
