The DIRECTORY command produces its listing by looking at either
    the actual channel queue directory tree on disk, or by looking
    at the queue cache database. The VIEW command controls which is
    used. By default, the view is the channel queue directory tree.
    Issue the command,

    qm.maint> VIEW DATABASE
    qm.maint>

    to switch to viewing the queue cache database. The command

    qm.maint> VIEW DIRECTORY_TREE
    qm.maint>

    will switch you back to viewing the channel queue directory tree.
    Issuing the VIEW command without any parameter will restore the
    default behavior and is thus equivalent to the VIEW DIRECTORY_
    TREE command.
