Just wondering if there's some sort of middle-layer, or common stub source for various filesystems? It seems more like they are all separate from each other. Not that it matters much. I suppose dos and iso9600 covers most of the cases where foreign filesystems are concerned. It would be good to have some documentation about the dos filesystem. I'd like to modify it for personal use. The idea is to add attribute emulation by relaying attribute calls to the boot disk, similar to my attribute library (http://www.bebits.com/app/3683) but transparent. Marcus
