file

    Specify a file (or list of files) with a full file specification
    or a logical name. Also, indirect command file may be used,
    e.g.: DEFRAG @DEFRAG.COM(/DEVICE=device). Thus, it is possible
    to generate a list with SEARCH device/OUTPUT=file and use that
    file as input to the DEFRAG command. The list generated by DFU
    SEARCH will contain the device name in the file specification.
    If there is a list of file from another source which does not
    contain the device name, the /DEVICE qualifier must be used to
    append the device name to the file.
