Abstract
The invention describes a method of updating content of a portable device (1) with a file system (14) for managing the content (F1, F2, . . . , Fn), an associated file system table (2), and a content database (3) for presenting the content (F1, F2, . . . , Fn) according to content metadata (M1, M2, . . . , Mn), which method comprises establishing a connection between the portable device (1) and a main device (4), replicating at least part of the current file system table (2) to give a primary file system table replica, modifying the content (F1, F2, . . . , Fn) of the portable device (1) by means of the main device (4), comparing the modified file system table (2′) to the primary file system table replica (2) and updating the content database (3) of the portable device (1) on the basis of the comparison results. Furthermore, the invention describes a system (5) for updating content (F1, F2, . . . , Fn) of a portable device (1), and a portable device (1).

11. A method of updating content of a portable device (1) comprising a file system (14) for managing the content (F1, F2, . . . Fn), an associated file system table (2), and a content database (3) for presenting the content (F1, F2, . . . Fn) according to content metadata (M1, M2, . . . Mn), which method comprises the steps of:
-
establishing a connection between the portable device (1) and a main device (4);
replicating in the portable device at least part of the current file system table (2) to give a primary file system table replica (2′
);
modifying the content (F1, F2, . . . Fn) of the portable device (1) by means of the main device (4) thereby creating a modified file system table on the portable device;
comparing in the portable device the modified file system table (2) to the primary file system table replica (2′
);
updating in the portable device the content database (3) of the portable device (1) on the basis of the comparison results. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A system (5) for updating content (F1, F2, . . . Fn) of a portable device (1), comprising
a file system (14) in the portable device for managing the content (F1, F2, . . . Fn) of the portable device (1) and an associated file system table (2); -
a content database (3) in the portable device for presenting the content (F1, F2, . . . , Fn) of the portable device (1) according to content metadata (M1, M2, . . . Mn);
a replication unit (6) in the portable device for replicating at least part of the file system table (2) to give a primary file system table replica (2′
);
a main device (4) for modifying the content (F1, F2, . . . Fn) of the portable device (1) thereby creating a modified file system table on the portable device;
a connecting means (10) in the portable device for establishing a connection (7) between the portable device (1) and the main device (4);
a comparator (8) in the portable device for comparing the modified file system table (2) to the primary file system table replica (2′
);
an update unit (9) in the portable device for updating the content database (3) of the portable device (1) on the basis of the comparison results.
