Transfer todo/calendar data Linux <--> Z

Hello,
Sorry if these was asked before. I've looked through the archive and 
everything and there was just a whole bunch of information about synching 
with linux, but haven't found the good solution. Plus, I've been "out of the 
loop" with the Z stuff for a while.

What I need is pretty simple. 
1. I have my calendar/todo list on my desktop as a standard iCAL (.ics) file. 
How do I put that to Z? I don't need to sync or anything, at this point. 

2. Also, the other way around, where is the file that define todo/calendar in 
Z get stored in, and how do I transfer it to my desktop as iCal format?

I guess I don't really need to synz at this point. I can for example use my Z 
as my central place for all scheduling/Todo, and then just have a mechanism 
to transfer it as iCal to desktop, as there are many-many program that can 
read iCal.

Any help here? Thanks a lot.
