• Problem: PIM (Personal Information Manager) items sent from Windows 7 operating system cannot be
received correctly into the address book of any other Bluetooth-enabled device.
Solution: Windows 7 operating system sends PIM items in XML format, but most Bluetooth-enabled
devices handle PIM items in vCard format. If another Bluetooth-enabled device can receive a file
through Bluetooth, a PIM item sent from Windows 7 operating system might be saved as a file with
the extension .contact.
