/IGNORE
       [NO]IGNORE

    Ignore "special" files that are likely to have some blocks with
    different data. These differences, however, are not unusual and
    can, therefore, be ignored.

    Other special files are the following:

       SWAPFILE*.*
       PAGEFILE*.*
       SYSDUMP.DMP
       SYS$ERRLOG.DMP

    IGNORE is the default.
