Disklavier

Has anyone tried to use a flashpath floppy that takes smartmedia memory
cards into a floppy disk on a disklavier floppy drive? With this floppy
disk, you can have a 128mb memory card available through a floppy disk. The
main problem that I could see with this on the disklavier would be the need
to group files in folders. (not sure if this is possible) 128mb of midi
files all at the same level would be tedious to navigate.

The link below describes the disk and how it is 3x faster than a normal
floppy disk.
