How to restore it once you find it: http://www.mozilla.org/support/thunderbird/profile#move
The link you gave me is helpful. I'm OK up to step 4.
4. # In profiles.ini, locate the entry for the profile you've just moved. Change the Path= line to the new location. If you are using a non-relative pathname, the direction of the slashes may be relevant (this is true for Windows XP).
That's easier said than done. Path=Profiles/3ohgdixq.default is what it is as originally written, but the actual mail is in the folder Path=Profiles/3ohgdixq.default/Mail Is that what I need to put in the profiles.ini file ? (I think I've somehow solved the earlier problem of not being able to save it) The reason I ask is that a gmail pop I added as a test is in the Mail folder and works with Thunderbird, but the other accounts in the profile do not show up. That's why I question the need to change the profiles.ini file.
5. # Change IsRelative=1 to IsRelative=0.
I tried this without good effect. But after a little research, I know these factoids:
IsRelative=1 refers to the expected or "default" folder path that would be relative to the operating system, e.g., Path=Profiles/xxxxxxxx.default would be C:\Documents and Settings\<user name>\Application Data\Mozilla\Firefox\Profiles\xxxxxxxx.default for a Firefox profile folder in Windows XP.
IsRelative=0 refers to a custom profile location such as Path=D:\Mozilla\Firefox\Profiles\MyProfile
StartWithLastProfile=1 indicates that the "Don't ask at startup" option is selected.
Default=1 refers to the last selected profile.
Now I'll see if I can get this turkey to fly.
6. # Save profiles.ini and restart Thunderbird.
Back to Square One.
