Interesting that it wouldn't use the CP/M file system.

http://en.wikipedia.org/wiki/File_Allocation_Table has all the details you'd need.
There were some dos copy tools (doscp) for linux and unix ages ago that would do this, but I can't seem to find source to it online. Probably because these days they're in the file system drivers instead.

Try this guy's source: http://www.zws.com/products/dosfs/ - looks like it might have what you need.

You might also want to look at the freedos sources.
