Don't get too excited just yet, respite.
You have NO idea what state those files are in. There's a good chance they are more corrupt than Bush and his administration.
I was, after your last post, going to suggest that you wait till you got your new computer and try the master / slave option (slaving your old drive to the new one).
That way you could **TRY** using either the import option in your new setups Outlook Express, or at least, try dragging the files / folders into your new PC's untouched OE. Trying to keep directory structure.
I have no idea if that would work, but looks like you only have a one shot deal with your friend at the moment.
Files to be pulling off would be:
.DBX (email), .IDX, .MBX, .WAB (address book) and WA~ files.
But this is far from as simple as it may seem. If you have Outlook installed and used, then the you may need .PST and .CSV files. A lot of these files should be mentioned in the above links.
I'm not on a machine with either OE or Outlook, so can't be anymore help, specially regarding the directory structure. And I've never actually tried rebuilding the email and address book part of OE like your attempting to do.
Let's hope you get a break and the files aren't worthless and corrupt, and it's more or less a straight swap into the relevant directories, assuming your running the same versions of OE.
Someone around here may have encountered this particular scenario before. Like I said though, if the files are corrupt, it's futile anyway. Hope you drop lucky.
Personally i'd pull the files off and stop using the drive -- get the new machine and and slave the old drive to the new one and try an import from within the new OE, also try dragging the entire directory structure over (replacing the new one).
