I’m curious: if both suites work correctly with .odt why insist on .doc?” and “Can you share an example of a non-working file?”
Good points.
I have collected an enormous amount of historical information on families and events in separate files. The data came from searching and translating old documents from many English archives over a long time. No doubt other people could do the same but if I’ve done it why shouldn’t they benefit. I’m often asked to comment on family names and events which I’m happy to do. I’m trying to protect it for posterity. But if I should fall under a bus my files would languish on my computer. To whom would they go? You can’t be sure. Trouble is that most people are not familiar with .odt files because they do not use Openoffice or LibreOffice. They might have old Word or other software which won’t open .odt files. I’ve been trying to preserve my information in .odt and .doc formats to cover these eventualities.
The file in question is very dear to me as it is to do with my property and the families that used to own and occupy it. I’ve had to go back to the 1400s to track their family events. It’s huge and contains many footnotes, inserted images and much analysis. It’s a ‘life’s’ work actually and I would hate for it to become corrupted and lost forever.
Now, every time I update it I convert it to a pdf which seems to be a common mode of exchanging documents.
