Thunderbird import can't find Eudora files - all installations are normal - what will work?

Question

Use import function - either 'import everything' or 'address book' and 'mail' separately - in all cases no files are found - all systems have basic installation - eudora version 7.1.0.9 (sponsored mode) - thunderbird 24.5.0 - have searched for help, but nothing seems to help

Answer 1

As I said, I have been running Eudora for years - at least three years on Windows 7.
My use of Eudora is very basic, but it does freeze (not respond) occasionally and I have to restart it. But I never loose any data.
The path to my address book files: NNdbase.txt and NNdbase.toc and sub-folder called "Nickname" is as follows:
C:\Users\apex\AppData\Local\VirtualStore\Program Files (x86)\Eudora
I created the following text file:
Windows Registry Editor Version 5.00
; Adjust C:\\Path\\To\\Folder below so that it points to your Eudora data folder
; with your nndbase.txt and nndbase.toc files and/or your Nickname sub-folder
[HKEY_CURRENT_USER\Software\Qualcomm\Eudora\CommandLine]
"Current"="Anything C:\\Users\\apex\\AppData\\Local\\VirtualStore\\Program Files (x86)\\Eudora Anything"
Saved it as 'Eudora-to-Thunderbird.reg' - and double-clicked it. It executed successfully.
Using Mozilla Thunderbird 2.0.0.24, I tried the Import function & instead of the 'no file' message, there was now a Browser pop-up.
I was not able to navigate the pop-up browser to the Eudora folder above.
I created another folder at 'C:\apex\My Documents\Eudora to Thunderbird', copied the contents of the above folder and navigated to the new folder.
The Import now worked!!
I still do not understand why the .reg file did not work.
