FAST wizard, FASTconv.exe Need to extract dbx files

OS WinXp Pro

I have used the 'File and settings transfer wizard' (start> All progs>
Accessories> System tools) to collect my data from Outlook Express (and
perhaps some others - can't remember).

Anyway. Now I've come to import the file onto a clean hard drive and OS, it
won't import. (I don't want to explore why it won't import, as I've already
wasted too much time on that route)

So. I'm now left with two files from the export, one being IMG00001.DAT
(approx size 50M). After various searches it would appear MS used to provide
a small prog (you had to request it) with the file name of FASTconv.exe
(runs in DOS) which verifies the DAT file integrity (by using various
switches - no I'm not that clever, I copied and pasted instructions I found
to verify my data) and exports the data as separate data files.

Although the data is there, its not in an instantly useable format. Does
anyone know of a way to just export the dbx files, so I can do a more
conventional way to import my messages in to Outlook Express?

I look forward to any help anyone can give, so thanks in advance.

John.

PS
I'm based in the UK (on dialup, not BB) and would consider using a data
recovery company at a sensible price who have worked on the above files
before. I have spoken to several today who didn't convince me that they knew
anything of the above files.
