I found them easily, and saw that since 2004 I had created PDFs of all the correspondence I sent, so I had that plus the original word processing format.
I could see that I had files going back to the original purchase in 1994. Unfortunately, they were unreadable. Whatever word processing programme I used back then is long since obsolete.
I've no doubt that the more recent files will become obsolete eventually, as will PDFs.
I wonder how much collective data, information and knowledge will be lost because of this sort of thing?
