DOS ain't dead - exFAT specification

exFAT specification (Developers)

1) The Linux alfa sources for exFAT moved here>
http://www.munted.org.uk/programming/exfat.tar.bz2

2) I found another analysis of exFAT
http://www.sans.org/reading_room/whitepapers/foren...gineering_the_microsoft_exfat_file_system_33274

Sooner or later will the support of exFAT be necessary.
ExFAT is aimed to flash drives. It is cool that Bret's drivers support not only INT21h functions like Georg's drivers but also INT13h so the support is possible.

In the first phase is even the driver not needed.
It will be enough, as a first step, just to add function inro some file commander (like Necromancer's DOS navigator or DOSzip commander) for mounting such drives.
