The Bat! is a powerful, highly configurable, yet easy to use, email client for the casual user or the power user, the home or the office. You can download TheBat here: http://www.ritlabs.com/
By default, TheBat address books are stored in the files with .ABD extension in MAIL subdirectory of TheBat. After check results export, you must restart TheBat to load updated address book. When AMV exports results, it deletes emails from contacts according filtering settings. If contact will contain no emails then contact will be deleted too.
We recommend making backup copy of your address book before check results export.
