>The new extended directory entry, sure (and not the FAT). Though, it must also keep the old structure to keep compatibility - when I write something to a floppy, it shows the correct time when read from as old as a DOS5.0 machine.

Hi Dragan,

I'm not completely sure, but this might only be the case if you're running in MS-DOS compatibility mode. In writing to the floppy, I would guess that it checks the file system, and if necessary, writes to it in that mode.
