Here a more detailed answer:
If you see the zaurus ics file in your windows device in the local file system, you can easily sync.
Create a new sync profile, choose as \"kind\" Local file and as file the ics file, of course.
If the zaurus is accessable via network, e.g. via ftp ( if a ftp server is running on zaurus) , you can copy the zaurus file to your windows device with the system command
ftp ....
A system command is a command, that you can execute from the console (DOS-Box) and that moves \"somehow\" your remote file to your windows device ( and , after syncing, back to your zaurus ).
