Okay...so no one at this forum can help answer this question?

How did you transfer the profile? That may explain the issue. And why are you keeping the NSTMP files? My understanding is that NSTMP files are corrupted attempts to compact and can be deleted.

so no one at this forum can help answer this question?

No… well… at least I, for one, can't…

You talk about some local archive gone from a computer as a result of having copied it to another, which makes no sense whatsoever to me, and about some missing NSTMP folder, as if it was supposed to be a common folder, but that's a folder that shouldn't be there in the first place (if present, it would be the result of some failed folder compaction attempt)…

So I for one don't know what to make of your post and cannot help… :)

Hi David

Thanks for your email. To elaborate, I had moved from Eudora email app to TB some time ago, but thought it was wise to keep the Eudora emails handy. Since I stored my TB archive locally on my PC, I figured to do the same with whatever TB could make out of my Eudora files (though I never actually tried to retrieve any of them.) Recently I moved my TB and profile to a new PC. Now my archives are there as webmail, like before, my my local folders are gone -- both from the old PC and the new one.

Are the folders in the profile on the old PC? If so, there was an error in the transfer. Here are the steps: Here is the link for moving a profile in Windows when installed in default location:

here is the info in brief steps:

1. ensure thunderbird is NOT running on old machine
2. enter %appdata% in search window on task bar and press Enter key
3. this should open windows file explorer in Appdata\roaming folder
4. highlight the Thunderbird folder and copy to external media
5. ensure thunderbird is installed on second computer and NOT running
6. enter %appdata% in search window on task bar and press Enter key
7. you should be in Appdata\roaming folder , copy&paste the exported Thunderbird folder there. This may prompt to overwrite an existing folder of same name. allow it
8. start thunderbird and all should be there
