       /MOVE
       /NOMOVE

    Controls whether movefile operations are enabled on the specified
    file.

    When you create a file, movefile operations are enabled on that
    file. You should disable movefile operations on specialized
    files that are accessed other than through the XQP (such as files
    accessed through logical I/O to a disk).

    Note that movefile operations are automatically disabled on
    critical system files. Do not enable movefile operations on these
    files.
