Well, the strength is that you don't remember the directory contents, only the hashes, diroffset and name length; this means nearly no memory use. Its also authorative: not found in the hash means its not in the dir. > I think it should be considered along with ext3 approach. What is is the ext3 approach? What is different compared to ext2?
