>>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.

Applies to all floppies, and works even if you boot your W95 machine from a 3.3 (well, at least I tried with 5.0 and 6.x) system floppy - you still see the old DOS file names, dates and times. That's compatibility.

When W95 first came out, I've read something about the long file name structures and other dirty tricks - one directory entry now takes more old-fashioned entries, where the last one in the line plays the role of the 8.3 entry, and the others are back-linked into it, and contain the new info structures (long file names, extra datetimes). The new entries have some impossible combination of flags (vol, dir and hidden at the same time, I think), so the old file systems don't see them. Investigating the whole matter would probably take some time digging up the docs (or fooling around with a disk editor), but I think I got the story right.
