That is a surprise! Mmmm, one was starting to look at Mac, but having invested money and time in learning (about 10% of) Word, I'm not about to downgrade.
When I got the zip open, there was a LOT of detritus. Three folders - Two called Desktop, and in the second of the two was the .docx file However, in one of the others, there was a _XXXX.docx file of 1k or less.
I asked him if he could learn (I'd sent him that link) to just send the one relevant file to folks. That was pushing it a bit as he's only just learned to open the lid.
