Method and apparatus for synchronizing how data is stored in different data stores
First Claim
1. A method for at least partially synchronizing a first data store residing on a first device and a second data store residing on a second device, the data stores each being used for storing data as data units in folders, the folders in combination defining a data structure, the method comprising:
- the first device sending a message to the second device;
wherein information about data in the first data store is transmitted in said message, and information about a change in the data structure of the first device is also transmitted in the message in an element or field of the message; and
further wherein said information about data in the first data store is placed in the message in an element or field different from the element or field where the information about a change in the data structure is placed.

Abstract
A method (and corresponding equipment and computer programs) by which a first and second device (11 12) synchronize how data is organized as folders in respective first and second data stores (11c 12c) maintained by the devices (11 12) based on exchanging messages (21) including data identification elements (28 29) that refer to the folders, with the data identification elements (28 29) provided in the message external to any reference to data units; or, more generally, based on the first device sending a message to the other and including in the message information about data in the first data store and also information about a change in the data structure of the first device, wherein the information about the data in the first data store is placed in the message in an element different from the element where the information about a change in the data structure is placed.

15. A device adapted for at least partially synchronizing a first data store residing on the device with a second data store residing on a second device, the data stores each being used for storing data as data units in folders, the folders having interrelationships and so defining a data structure, the device comprising:
-
means for sending a message to the second device;
wherein information about data in the first data store is transmitted in said message, and information about a change in the data structure of the first device is also transmitted in the message in an element or field of the message; and
further wherein said information about data in the first data store is placed in the message in an element or field different from the element or field where the information about a change in the data structure is placed. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
