No, raw-win32.c is not the right place to do this.
If I create a split file with VirtualPC under Windows 2000 and then
transfer it to my Linux host then QEMU should still be able to read
the file. This feature is not tied to the host platform or file
system.
It is block/vpc.c that needs to handle this. The first file can be
opened as normal because it has the header. The code can detect that
the image file is split and simply open additional files as necessary.
