Casio CZ/ VZ/ FZ - Pro Series

Hello All
Just received a extremely tidy FZ-1 from the bay. As sweet as can be
expected. The backlight has gone but the drive seems fine. My FZ-10 is
with my tech, hopefully returning with the PC drive upgrade.

Q: Does anyone know where I can find the optional Casio software
programs for the FZ?

NoteIt's superb Casio FZ-1 Page has some utilities, but the programs
I'm after are'nt there.

The program I am most interested in is the "OS B Loop Optimizer" which
apparently optimises load times, cross fades, and hopefully file
sizes. It also has a disk copy tool.

The other 2 disks are

OS A Disk Directory Tool- Sounds handy.
OS C Playbacker - If this is some kind of auditioning program, it
would also be very useful.

Does anyone have this software or know where I could find it?
Are they useful?

Thanks
Jeremy
