Here is an AppleScript to export all your
Address Book Contacts.app contacts to a single vCard format (vcf) file. The resulting file can be imported into other contact programs on both Mac and PC computers:
set myBackupName to "AddressBook.vcf" -- Add timestamp and Documents path set myTimeStamp to (year of (current date)) & (month of (current date) as number) & (day of (current date)) set myBackupPath to the (path to the documents folder as string) & myTimeStamp & "-" & myBackupName as string -- Remove any existing back up file created today tell application "Finder" if exists (file myBackupPath) then delete file myBackupPath -- move to trash end if end tell -- To work on Mac OS X 10.4 - 10.7, change "Contacts" to "Address Book". tell application "Contacts" -- Create an empty file set myBackupFile to (open for access file myBackupPath with write permission) repeat with per in people write (vcard of per as text) to myBackupFile end repeat -- Close the file close access myBackupFile end tell
This AppleScript creates a single file in your Documents folder; the created file is called "yearmonthday-AddressBook.vcf".
This AppleScript avoids calling out to do shell script and uses only built-in AppleScript commands.
Update: Thanks to Adam van Gaalen for his feedback and improving this AppleScript. Thanks to Adam's testing this AppleScript will now work all the way back to Mac OS X 10.4.11.
