Hi,
Newbie here.
I am enjoying using knoppix CD and am very impressed it.

I have a few questions about the persistent disk image.
I havent tried to use it yet as I don't want my Hard drive to be alterd.

If I use my hard drive does it save the disk image as a file or does it add a new partition?
I understand I can also use a USB memory stick for a disk image, would the image be saved as a file and would I still be able to use it under windows?

Also what information is stored in the disk image? If I set up my email and save a disk image would that data be stored?
If I installed a new program could that information be stored too?

What I am thinking is the posibility to use a live CD with a USB memory stick and use knoppix as if it were installed on my hard drive.

Also one more unrelated question, what is the diffrence between the live CD and DVD? I assume the DVD has more software pre-installed? is it woth using the live DVD for a newbie?

Thanks for your time.
