Aah! Thanks Richard,
I've had a closer look now (I'd only quickly skimmed the SD folder).
I took the file numbers to be the same as the sheet references on the
First Series sets - don't know why - especially as they are derived from
Just as a matter of interest, I'm viewing the files in Openoffice. The
drawing app. provides a quick and easy way to view the files graphically.

Presumably any ones which are missing are the ones which are out to sea and
therefore have no contours in them?
e.g. the 100x100km grid square "SV" only contains sv80.dxf - as that's the
only square which has any land in it (the Scilly Isles)
For the ones on land - there should be 25 files per larger-grid square.,
i.e. each file represents a 20x20km square.
I've by no means checked every one on my download, but a look at quite a few
squares show that I have all the ones I expcet to have for those squares.
