The size of the section (for object files) or the
size of the initialized data on disk (for image
files). For executable images, this must be a
multiple of FileAlignment from the optional
header. If this is less than VirtualSize, the
remainder of the section is zero-filled. Because
the SizeOfRawData field is rounded but the
VirtualSize field is not, it is possible for
SizeOfRawData to be greater than VirtualSize as
well. When a section contains only uninitialized
data, this field should be zero.
