It's an Explorer trick. Even with the options to view system files and hidden files, Explorer will not show you your own IE6 History in this format. If you look at the History folder of a user other than the currently logged in user, you'll see these "special" folders. You can also load up cmd.exe and cd "C:\Documents and Settings\username\Local Settings\History\History.IE5". It's really fricked up. Even cmd.exe gets confused with some things here. If you chdir up once to (Local Settings\History) and do a 'dir', it'll tell you file not found. Even though you can still cd to History.IE5. That's Microsoft for you.
