Command F - freshen files within an archive
Update files in the archive only if they are older than the files to add. This command will not add new files to the archive. This is the command line equivalent of the command Add to archive with "Fresh existing files only" update mode selected in the Archive name and parameters dialog.
Because archive volume modification is disabled, this command is not applicable to volumes.
