I've tried everything I can think of, but none of it works. It
either creates an error or fails silently.
Here is one example:
tell application "Address Book"
set daName to name of person 1
tell application "Finder"
make new file with properties {name:daName & ".vcf"} at folder "Dora"
set dest to the result as alias
end tell
set foo to vcard of person 1
save foo in dest
end tell
I've tried it without creating the file with the Finder.
