Moving mail, filters and addresses from Slack to Kubuntu

I have slack 12.2 (KDE 3.5.10) on one partition and Kbuntu 
6.10 on another (KDE 4.2 I think.) I want to import all my 
filters, my directories and my emails from the Slack 
partition to the Kubuntu partition.  Now there are import 
functions of course. But where do I look for the filters in 
particular in the old user directory? Where are they 
hidden?
