"but why can't I read or edit my M$ Word documents from 1990 using M$ software today?"
I thought it worked the other way round until MS got their arm twisted to sort of standardise the format. If you had Word x you couldn't read a .doc written with Word X+1 so you had to buy Word X + 1just to open documents someone else sent to you. But Word X + 1 had to be able to (usually) read a .doc written by Word X. Not even MS could have got away without that. I did come across one .doc with macros that was absolutely version specific and would simply hang the entire box that ran any other version.
