Re: There Is Signal......And Then There Is Noise!
If you haven't bothered to save your 1990 ultra-historical document any other times, then maybe it's not so ultra-historical. True, you can find eight original copies of the Magna Carta out there, but I can also find millions of newer copies which are identical because it was important enough to preserve. That also means that, if some disaster had destroyed those eight originals at some point, we'd still know what the Magna Carta said. You probably can't find any of the original copies of the Zimmermann Telegram either because the German copy was probably destroyed and the British-intercepted version was a temporary document sent for decoding, but it was historical, so we made a copy and stored that.
My three "un-natural acts", which would get you the content of the file for copying and preservation, are not hard to do now and will continue to be achievable with little technical knowledge. I'm not sure what makes them so unnatural since they basically boil down to reading the file and seeing what it says, either using the original software or something that reads its files. They won't make it simple to recover any document 800 years hence for the same reason that I can't get you many other documents from the 1200s today: if the file is gone, it won't help, if the file can't be located because it wasn't labeled, it won't help, and if you can't be bothered to preserve something, it won't help. If you are aware of any important documents that are in 1990 Word format, and you think they are worth preserving, then you can perform these acts and preserve them. I'm willing to volunteer to do that for anything sufficiently important, just let me know. The data that nobody chooses to do that with is probably going to get lost, just as the paper that was burned because making a copy and moving it wasn't considered important.
As for Micrographx Designer, here you go. If you didn't bother to save your data when you stopped using the program, even if you're regretting it now, it probably means that it wasn't as important as you think. If it was, you would have done more to keep it. Of course, we've all had the experience of losing something we wish we hadn't, and we respond to that by putting more effort into retaining access to it. A file that is very old is not hard to preserve, just as a piece of paper from a long time ago isn't hard to preserve. That some old paper is around does not demonstrate that it is any better at it, and I am confident that, if there are humans in 2800, they'll have lots of files created during our lifetimes available for perusal. It just won't be very many with my name on them, because most of the files I make are not historically relevant.
