That's of course another way to get to the drive - well done!
What do you mean by "recover them"? Recover them to where? They should be stored as .eml files. Go further in that directory to Local Folders and you will see the various folders and inside each will be the emails as .eml files. THOSE are your emails - not these other files. Those are what you want to recover.
The simplest answer is just to copy them to some external storage device like a flash drive and then go to another computer with Windows Mail and Vista, create the proper account and login to it so the Local folders are for that account, go to the storage location on that PC and copy the saved emails to the appropriate folders in the computer (I'd copy the whole Local Folders directory to the flash drive and then copy the contents of the individual folders directly to each separate folder - do not just copy the entire thing in one action or I believe you will create duplicates which you may not want and may be hard to properly consolidate).
As far as I understand, that should do the trick. When done, open Windows Mail and those emails should be there. If not, post back and I'll do further research on the problem. We may need to copy the entire directory to the new computer and completely replace whatever is there with the new information (but then that would be a problem if you are using Windows Mail on the other computer). I'm not positive as I've never had to do it this way before but we'll try to be sure we're careful and cause no problems that can't be easily and quickly corrected.
The proper way would be to import/export the files, but you can't do that without the program running on the source drive and obviously that isn't possible here.
I hope this helps.
Good luck!
