In the past I have been using a PHP-Script to read data directly from the *.mab files in my profile.
I tried the same with SELECTing the data column FROM the table object_data in the cardbooks sqlite-file. Most of it is readable text, but it contains weird characters – even in names, that consist only of standard a-z characters.
Does cardbook use some special algorithm to “compress” something here or is this Thunderbirds doing?
Alternatively is there a way to automatically export/backup the contacts in text format?
