An untitled data file opens in the CardScan window. 2.From the File menu, I chose Save as, and entered name for data file, and looked location where to save it. Assume should be My Mac Contacts. However cannot find a location which to dedicate where to save the contacts, so it is possible to update and synchronize the device software with Address Book. Can anyone help?
