/SIZE=size

    Specifies the target volume size for a partition file creation.
    Must be specified with /CREATE.

    Within the range of volume capacities restricted to use of
    the FAT12 volume structure, the specified size must match the
    capacity of the recognized floppy devices. Typical floppy disk
    capacities are 720, 1440, 2400, 2880, and 5760 blocks, with the
    2880 block double-sided high density 3.5 inch floppy disk being
    the most common choice.

    To create a FAT16 volume, the specified size must be between
    8400 and 1048576 blocks (512 megabytes) for the default FAT16
    structures, though this tool does allow volumes to be FAT16 up to
    4194304 blocks (2 gigabytes); up to the theoretical limit of the
    FAT16 volume structure.

    Attempts to create volumes above 2 gigabytes in capacity are
    rejected; this is a hard upper-capacity limit within this tool.
    Volumes of 2 gigabytes through larger must utilize FAT32 volume
    structures, and this tool does not presently support the creation
    of nor any operation with FAT32 volume structures.

    Must be specified only with /CREATE.
