Data storage
The memory of G900 is divided into:
• A Phone memory with a phone part, and an
'Organizer' part running Symbian OS. The
‘Organizer’ part consists of a RAM (Random
Access Memory) memory that is controlled by
the Symbian OS, and a 256 MB flash memory.
The flash memory is split into approximately 96
MB for operating purposes and up to 160 MB
for storage of user data, additional languages
and settings such as the active theme. This part
behaves just like a normal disk drive. The fold-
ers can be viewed and managed from the File
manager application or from a connected com-
puter.
• A Memory Stick Micro™ (M2™) memory card of
maximum 8 GB (not included at delivery) for
user file storage. This memory behaves like a
normal disk drive. It can be accessed as a USB
mass storage device from a computer, allowing
fast transfer of files.
User storage
The user storage space (C: drive) is shared across
applications without any imposed restrictions,
apart from the whole space becoming full.
Unlike a computer, the user does not need to be
aware of the underlying file 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.
Additional storage space is available by using
memory cards. Memory cards of up to 8 GB
capacity are supported. Any number of memory
cards may be used for storage. See “Memory Stick
Micro™ (M2™)” on page 38 for more information
on how to use memory cards when exchanging
data with other devices.
Depending on the application, data can be
beamed, mailed, uploaded to the Web, transferred
to a computer or moved to a memory card in order
to archive and create free user space on Sony
Ericsson P1. See “Synchronization” on page 44.
User storage configuration in
G900
Applications and information are placed in the
internal storage of G900 in the factory. This
provides sample demonstration, educational,
multimedia and fun content so that G900 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, that is, 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 backed up data in G900 using the
PC Suite for Sony Ericsson, then the C: drive can
be restored to the state 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.
