All ADFS does is read and write sectors using built in IDE and floppy 
disc controllers, it has no knowledge of disc formats.

All the formatting is handled by the Filecore module. The way to get 
Filecore to understand a Filecore formatted file image, is to implement 
a FileCore Image Filing System. It's very straightforward, all the hard 
work is done for you, you just have to open a file and read & write sectors.
