It is usually part of the hardware instance.  Look in the com
port browser.

hardwareinstance
USB\VID_1004&PID_6000&MI_02\SERIAL_NUMBER_02
This is how the device is named internally. For example USB devices
include the vendor (VID) and product (PID) identities

Every LG phone so far has been VID=1004, PID=6000

That is just what the modem gives.  You can't actually get it via the USB
diagnostics interface.

You have to look in the driver hardware instance bindings.

That file serves a different purpose.  I think it lists all directories
that could be deleted if you wanted to do a factory reset.  Or maybe
it is the directories that should be counted if you are trying to figure
out how much space has been used.

Yet another naming convention ...  On other LG phones it is user/sound/ringer
and brew/shared respectively.

Yet another different scheme.  And they love duplicating information (eg
file size is stored in two different places).  I wonder how they map
the files into phonebook entries.  On the other phones, there is an 
index file which maps numerical indices into the filenames.

Can the directory name include the extension (eg could you name it example.jpg)?

Sounds like no index at all.

That is in fact exactly how the other phones store the pim.  Can you set the
phone type in BitPim to be VX4500, and then request the phonebook?  Please
email me the last 4 packets from the protocol log.
