Microsoft guides me to transfer my address book with file extension .pab from my old computer with Outlook 2007 to my new computer with Outlook 2010. Yet there is no such file extension in my folder, merely the following ten:
6 .pst files, some have been automatically transferred to my new computer
2 . OBI files, each with 2KB
1 . DAT file with 1KB
1 . KFL file with 4KB
which would be the one with my address book?
