“Great”.

No offence to anyone, but I would not consider the performance of MS office to be great.

I guess it's comparative, but then I compare to its previous editions which used a sliver of the resources to accomplish 95% of what modern o365 does.

> previous editions... used a sliver of the resources

Well of course, but given that the previously employed technique was blitting, fliedumping memory areas, you can't be more efficient than that. Using XML is for transparency (readability).

(And, note, in context, I regard the ms office file format as lousy. The OpenOffice/LibreOffice format is good.)

I don't think your parent comment was talking about the resources involved in saving a file, but rather the resources involved in running the software.

		Thank you, probably so, but in that case I cannot see how said comment is consistent in the branch ("about file formats") - I do not get how it would follow.

Office documents since the 2007 have used a zipped XML approach. Just take an .docx and open it in 7zip.

EDIT: Narrowed the date.
