Here's the thing. The strange filesystem occurs when you burn a CD with CDRWIN using the Joliet filesystem. CDRWIN's help file states
Note: A Joliet disc contains both the short and long versions of all filenames, so that the disc will be compatible with older DOS and Windows 3.1 based systems.
Well if that is the case why on earth is the Joliet (short) file system in existance at all considering it is pointing at the ISO 9660 tables with the short names. What added functionality does it give? If compatibility is the purpose does the ISO 9660 file system not give DOS & Win 3.1 compatibility on its own?
