/UNITS=keyword
    Allows you to override the current default specified by SET
    PROCESS/UNITS so that you can display disk free space in your
    choice of blocks or bytes. (/UNITS is functionally equivalent to
    /SIZE.)
    The following keywords are valid with the /UNITS qualifier:
    BLOCKS, BYTES.
    If you specify /UNITS with no keyword, the default value is not
    changed.
    Note that you cannot use the /UNITS qualifier with the /FULL
    qualifier.
