No, simply copied the .html file - as worked in Moz on the Cpq's ME.
(I had supposed that "Export" merely obviates necessity of finding the sub-dir in which Moz keeps various data - then copies it to target. I mean.. straight 'html' - what massaging could it need?)

Will pursue anon, what with all the recent distractions.

Hmmm - boot CD a la Demo; run Moz - R/O all but one small HD partition, for data.

Later, retrieve what seemed worth saving from online session -- bug check, wipe partition -- for next session. Get Rich: sell Make-a-Doze-CD\ufffd from your OS-copy - safe browsing at last! . . .

[Why Not? Use all the other fancy aps - off-line; the only time Doze is ~~'safe']
(except from itself, natch.)
