The report option generates a file and free space report of the disk.
 Also a graph table is made which gives a quick overview on the free
 space distribution of the disk.
 Syntax :

    REPORT <device>/Qualifiers

1  –  Qualifiers

1.1    /APPEND

     /APPEND=filename

    Same as /OUTPUT, but the output will be appended to the
    file if it already exists. Thus output from multiple
    DFU commands can be put in the same output file.
    If the file does not exists it will be created.

1.2    /GRAPH

    /GRAPH
    /NOGRAPH  (default)

    This qualifier enables the graph output of the free space
    distribution for the disk. The default behaviour is not to
    display the graph output.

1.3    /OUTPUT

    /OUTPUT=filename

    This qualifier redirects the output from DFU to an output file.

1.4    /NOBITMAP

    Skip the bitmap statistics report.

1.5    /NOFILE

    Skip the file statistics report.

1.6    /NOVOLUME

    Skip the volume info report.

1.7    /STATISTICS

    /STATISTICS
    /NOSTATISTICS  (default)

    Controls whether cpu and I/O consumption of the
    command are shown.

1.8    /UNIT

    /UNIT=BYTES | BLOCKS
    /UNIT=BLOCKS (default)

    Report sizes in units of bytes. The default behaviour is to
    report sizes as block units.

1.9    /USAGE(=uic or identifier)

    Generate a diskblock usage report. DFU will report per
    UIC/Identifier the blocks used/allocated, and the number of
    file headers used. If diskquota is enabled a third column will
    be added to the report with the blocks used according to QUOTA.SYS.
    If an UIC or Identifier is entered then only that UIC will
    be reported.
    The diskquota used must satisfy the rule :

    QUOTA used = blocks allocated + # of file headers.
