Can I save settings on a local partition when using Live CD and Knoppix ?

In a way boot from the CD but also start up with my profile and setting lacated on a linux partition or Linux swap partion ?

I have Knoppix running now from my CD and very impressed with it and all the option that come with it on the 3.6 cd.

But if I download my mail for instance, this would al end up in a temp file I would image.

Is there some way to mount a bit of harddisk to save files on my pc or would this require a HD install of Knoppix ?

greets, Pierre
