White Paper W950
33 June 2006
Preliminary version - PA4
User storage
The user storage space on the phone memory (C:
drive) and Media memory is shared across
applications without any imposed restrictions,
apart from the whole space becoming full.
Unlike a PC, the user does not need to be aware of
the underlying filing system. Applications will
always store information automatically in the
appropriate folder, simplifying the management of
data. Third party applications may implement more
complex file management solutions where
required.
The W950 supports USB High speed data transfer
at 480 Mbps. In this mode, the phone is seen as a
USB mass storage device from the PC. The first
time the phone is connected to a computer via
USB, the user will be given the choice to enter
either normal mode or mass storage mode. The
mode can be changed at any time from the phone’s
control panel. When connected to computer in
mass storage mode, the Media memory and all
files stored on it are inaccessible from within the
phone and its applications. The Media memory is
accessible again as soon as USB is disconnected.
Normal mode must be used when synchronizing
PIM applications or making backups using the PC
suite.
User storage configuration in the
new W950
Applications and information are placed in the
phone memory of W950 in the factory. This
provides sample demonstration, educational,
multimedia and fun content so that W950 can be
used directly out of the box. Much of this can be
deleted by the user in order to make the space
available for personal use.
Action at master reset
Master Reset restores the phone to its purchase
state, all user data is deleted. When a Master Reset
is initiated the user can select to keep all user-
installed applications. Data can be restored as
follows:
If the user has previously backed up W950 using
the Sony Ericsson PC Suite, then the C: drive can
be restored to the condition it was in when the
backup was made. The exception is DRM Forward
Lock protected files which cannot be transferred to
other media and therefore not backed up.
Otherwise, data can be re-loaded from the Sony
Ericsson Web site.
Since Multimedia content is easily transferable
using infrared or Bluetooth™ wireless technology
beaming, it is simple to restore favourite content
from someone else's W950 (unless DRM pro
-
tected).
The 4 GB Media memory is not affected by a mas-
ter reset.
Folder view of internal storage
When viewed from a PC using Sony Ericsson PC
Suite, the 'C:' drive is named 'Phone Memory', but
only a subset of the folders is accessible from the
PC.
The 4 GB flash memory is named “Media Memory”.
On both the phone memory and the Media
memory, there is a folder for each media type:
audio, video and image. Documents are stored
under the 'document' folder. An 'Other' folder
provides a place for files that do not fit into the
other categories.
