This file contains all the installed application, configuration settings, your personal data, that you want add to the system and can not be stored in r/o Live Linux.
After boot process this file is integrated in the system with UnionFS.
Oh, I see! I am aware of knoppix-data.img and unionfs. I sometime switch to Pippy Linux to mount the Knoppix .img file, copy the downloaded files and clear and clear up the space of the ... .img file.
