       /DELETED
       /NODELETED

    Lists a directory of files that have been deleted from an RT-11
    device, but whose file name information has not been destroyed.
    The listing includes the file names, types, sizes, creation
    dates, and starting block numbers (in decimal, unless you also
    specify the /OCTAL qualifier) of the deleted files. The /DELETED
    qualifier is valid only with block-addressable volumes in RT-11
    format. The default is /NODELETED.
