Thanks very much for that Neil. I have already begun the task of
recreating the document, as well as installing a more rigorous back
up system. The experience has, however, been an insightful one, your
various comments giving me the knowledge me and perhaps others on
the list need to take action in the future. It has been a really
good illustration to me of what is so special about Linux and the
mailing list system. Thanks for that.<br>

Regards,<br>

I know I'm coming to this a bit late but there may still be hope. Linux
filesystems generally do not overwrite a file when you save a new version
of it, which means that your previous saves (or auto-saves) may still be
intact on the disc, even if not included in any listings. Photorec, from
the testdisk package, can recover all files on a filesystem, included
deleted ones. Running this over the whole filesystem will generate a huge
number of files, with meaningless names, but they should have suitable
extensions (the name is lost when the file is replaced but the filetype
can still be identified).
Whether it is quicker to trawl through the results of running photorec
than to recreate the file only you can say.
Note: you need to run photorec with the filesystem unmounted, I generally
use a live CD and save the results to a USB or networked hard drive.

<pre wrap="">I've had a look, and it appears that the file was truncated mid-write,
it's missing the end header, and an indeterminent proportion of the

map of liverpool, and which comprises nearly all of the what is
available in document, but has also been truncated within the file
itself. Apart from a couple of I can't find any text remaining in
the file either.
