Many thanks for your help everybody.
For other non-coders and programmers, here is what happened.

Correct. I saved what was visible on screen on the ARCHIVE pages - the
only place I know to read.
What I saw was a very very long string of letters with no spaces - yes -
like email, but I don't know any better.
Your clue suggested that I open the copied block (which I had wrongly
saved as sowt.diff in cinelerra-cv) in Thunderbird.

Thunderbird extracted my wrongly saved sowt.diff file. Hurray!!!!! - but
three lines at the top and one at the bottom had to be commented out ( #
) so that 'diff -Nau...' was the opening line. The new found file now
worked after a various re-installs.
Is there a FORUM that I have missed, rather than the ARCHIVES ???
Thanks to all.
