I have all my TT data files going back to the early days of TT. Also the original TT floppy discs. Extremely unlikely they will ever be needed, but I have everything just in case. I also still have an external floppy disc drive that handles both 3.5" and 5.25" floppies, unused for at least 30 years. Long ago there was only one TT program that handled everything, instead of the four or five now. I don't know if my present laptop has everything needed internally to upgrade to W11. I guess all I can do is to try it and see.
