What is the difference betwen the option of creating a Knoppix disk image and to Save conf. Despite saving configuration, is it used for anything else?
Also, does creating a disk image save only Klik, and some other files or the whole home folder? I'm confused mainly, because some of my files were saved just by selecting the Save configuration.
About the Disk image: How much space does it need on a Flash drive ( I have one with only 128 Mb), should I use the whole space or just part of it.

Thanks!
