recovering a backed up address book

Hi I used Cobian to backup and old PC running Windows 10. unfortunately this PC has now given up the ghost. I am trying to recover the old address book from the backup. I can find backed up files called abook.mab.bak and history.mab.bak. I have tried renaming and copying these files onto the new PC, but this does not seem to be work. Can you confirm that all I need to do is rename them and copy them. Also can you please confirm what folders I need to copy these files into. Cheers John

Chosen solution

On you new PC open Thunderbird and go to Help > Troubleshooting Information. Click the button "Open Folder" next to "Profile Folder". That's where the files should be copied to.

Now close Thunderbird, copy your old files abook.mab.bak and history.mab.bak into the folder you just opened on the new PC and rename these files to abook.mab and history.mab (means: delete the ".bak").

When you start Thunderbird on the new PC, these should automatically get converted to .sqlite files which is the new format for the address book.
