Need new disk image.

With PD 4 I have a disk image (C that contains the Windows OS and some other files. It expands, but it seems there is a 32 GB limit. How can I create another disk image (D? I need it because all my data files are network drives in OS X, and that is too slow for some of my applications.

Thanks.
