You do not try to map all 17GB at once, do you? You don't have that much
address space. When working with large files like this, you can use
MapViewOfFile and UnmapViewOfFile repeatedly to map small areas, or
views, of the file into memory.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
