Yes, depending on which axis of effiency one travels. Microsoft Word 4.0
(and 3.0 too, I believe) can store a multi-hundreds of kilobytes
document wicked fast by storing only changes onto an already present
file, instead of saving the whole thing out to disk.

This is really quite a neat trick. Assuming your editing isn't
usually as drastic as changing, "And I'm going to shoot you Monday"
to "And I'm going to have to talk to you Monday," this isn't a big deal.

The workaround isn't too difficult: it's called "Save As."
