Under 10.5.8 (in French), I re did tests with the document sent by the OP.
It's a docx file deprived of extension.
As is I was unable to open it receiving the "invalid format" message.
Screenshot done using the Open menu.
I retried after adding a dot at the end of the name.
This time, unable to open but no alert.
I added the extension and the docx opened flawlessly.
I exported it as .doc file.
With the extension it opens with no problem.
With only the dot, nada
Without the complete extension, one more time, I got the message : "invalid format".
Now, I will no longer waste my time about that.
I tried to help someone which refuse to admit what I discovered.
peter wrote that we were wasting time doing the things the wrong way.
As I didn't made conjectures but just made tests, I take that as insulting !
So I stop searching on a problem which doesn'(t matter for me as every doc arriving here is, normally, automatically redirected to the trash.
