Also, they can probably not publish it or release it as open source. The way I read it, that's not the case. It only applies to manufacturers of preformatted media and some consumer electronics. It doesn't seem to apply to somone writing a file system "driver", at least not from what I read (which was merely the email Amuary Jacquot sent to the list). Also; >time to use some other file system, such as ext2 or ext3... I can't see that happening. I've not looked at implementing ext2 / 3, but the reason people use FAT is it's simple. Unlike other FS (BFS, XFS, etc) which use complex data structures (Such as B+ trees), FAT is a simple singly linked list. Easy to implement on architecture with limited resources. -- Michael Davidson Fortune: Seleznick's Theory of Holistic Medicine: Ice Cream cures all ills. -- http://www.piclist.com hint: The PICList is archived three different ways.
