Casio CZ/ VZ/ FZ - Pro Series

Hi everyone!

I'm a recent owner of a CZ-101 (and soon of a CZ-1000... and maybe 
other CZ series model). I'm totally hooked to it. But that's not the 
point.

My problem is the following: how do one export/import CZ sysex file 
to/from the synth? A friend of mine gave me a bunch of sysex files he 
found on the Net (thinking it would be helpful/fun to me)... but what 
should I do to try them out on my CZ-101/1000??? 

Help needed!

Thank you very much.
