My understanding of background saving is that it doesn't keep the whole program busy when saving. In other words, you can continue working (adding text, formatting) while the save operation finishes.

I have no idea if background saving means anything in practice today (even with large documents), when computers have a lot of disk space an processor power.

Ahh, now I get it. For me it only takes a couple of seconds to save very large files so that's what was confusing me. MS must have left it in for people using older systems.

Many thanks.
