Well if you're talking about sharing the files between the two operating systems on one computer, then I would think that having a separate FAT32 partition to store the shared files would be the easiest approach. But having not used it, I'm only guessing.
I plan on running Windows off an external hard disk, using Macdrive with it, and back up my internal hard drive to an external one, thus eliminating the need for a backup partition.
