It seems that the feature of storing all the preferences in a plain folder has been stopped since KNOPPIX V6; venturing into minirt.gz may be the only way out.

A workaround (less ideal; requiring quite a bit of manual work) I can think of is to install KNOPPIX on the 2nd partition and the persistent partition on the 1st partition and to take advantage of knoppix-data.inf, so that KNOPPIX knows where the user's files are stored and Windows can also access those files.

An even less ideal workaround is to flip the Removable Media Bit (RMB) of the flash drive, so Windows will treat the flash drive as a hard drive and shows all the partitions in the Windows Explorer. Personally, flipping the RMB isn't my cup of tea as the RMB is embedded in the firmware of the controller and the firmware is often vendor-specific.
