  Determining last file access date? 
 The Question is:
 
How can I tell when a file was last accessed?
 
We have a system here which has grown in file quantity over a period of  6
 years and many files we suspect are no longer needed.
 
 DIR/FULL will show created and revised dates, but what if the file is viewed
 or accessed without any changes being made? Is this information available ?
 
We are reluctant to delete files without the knowledge of whether they are
 still being used for lookup .
 
Thanks in advance
 
 
 The Answer is:
 
  Use the file expiration dates mechanism. These dates are updated on
  file access (if necessary).  Please see HELP SET VOLUME/RETENTION
  for details.
 
  Part of the DII COE effort will more directly provide this mechanism
  within the file system.
