So interesting that someone was still using Twiggy FileWare disks even into February 1984.
Why? Sony 400K disks had less capacity, but everyone with a Lisa surely had either a ProFile or a Widget. So this must have been someone's backup copy, right? That's why they're all dated: because they're someone's point-in-time backup copy.
Second interesting point: starting bid for this auction was $349 and the auction duration is
only 1 day. Surely the seller knows he can realize a much higher final sale price with a 5 or 7 day duration! Why such a short auction which will only serve to limit the sale price???
