P800/P802
White Paper, January 2003
Note: The extensive MMI of the P800 means that it is impractical to hold many languages inside the phone, as is done for some other models.
The second 16Mbyte bank of flash memory is divided into two parts. The first 4 Mbyte is reserved. It is essentially an extension of the ROM area.
The rest of the second bank provides a ‘C:’ drive of 12 Mbyte capacity. This behaves just like a normal disk drive. Some folders can even be viewed and managed from a connected PC. In the Chinese version the reserved area is 7Mbyte and the C: drive is 9Mbyte
When a P800 is updated at a Sony Ericsson Service Point, or over the internet using the Sony Ericsson Update Service, all three banks of flash memory will be rewritten. User data that has previously been backed up to a PC can be restored to the C: drive afterwards.
User Storage
The user storage space (C: drive) is shared across applications without any imposed restrictions, apart from the whole space becoming full. For example, one user might use the entire user storage space for photographs, in which case over 200 can be stored. Another user might load a third party street map application and a number of street maps. In this case, the application will take up some of the storage space and so will each map. When space becomes limited, the user can choose to remove some maps.
Unlike a PC, the user does not need to be aware of the underlying filing system. Applications will always make sensible choices and store information automatically, simplifying management of data. Third party applications may implement more complex file management solutions where required.
Additional storage space is available by using Memory Stick Duo. A 16Mbyte Memory Stick Duo is included with the P800. Any number of Memory Stick Duos may be used with the P800. See ‘Memory Stick Duo’ later in this paper for more information. Memory Sticks up to 128Mbyte capacity are supported.
Depending on the application, data can be beamed, mailed, uploaded to the web or transferred over the link to a PC in order to archive and create free user space on the P800 – see ‘Synchronisation and Data Transfer’ later in this paper.
User Storage configuration in a new P800
Applications and information are placed in the internal storage of the P800 in the factory. This provides sample demonstration, educational, multimedia and fun content so that the P800 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.
