In the latest release of Thunderbird the main address book changed from *.mab to *.sqlite, and at least the install was kind enough to make a backup copy of the original file. Now for the question:

I use Thunderbird on both Mac and Windows. The only way to (now!) keep the address book in sync between the two computers is, when I'm done on the Windows machine I copy over the abook.sqlite file to Dropbox and then on the Mac copy the file from Dropbox to the profile location before starting Thunderbird and all is well. But that abook.sqlite file only covers the main address book. What's the file in that profile folder that covers the "Collected Addresses" portion. I'd like to keep that file updated between computers as well. Thanks,
