I don't see that this will solve the problem, as he still needs to handle t=
he FAT file system.

On another note people keep talking about FAT having  a 4GB limit - it does=
 for an individual file, but not for the disk size, Windows will format a d=
rive up to 32GB as FAT, special utilities will format larger drives as FAT.
