Abstract

L'invention concerne un procédé et un appareil qui permettent de gérer des fichiers de données d'une mémoire locale. Le procédé de gestion de fichiers de données d'une mémoire locale comprend les étapes suivantes: a) on télécharge au moins un fichier de données depuis un fournisseur de contenu, on stocke le fichier de données téléchargé dans la mémoire locale, et l'on forme une unité de liaison au moyen du fichier stocké; et b) à la réception d'une commande d'effacement d'un fichier spécifique contenu dans l'unité de liaison, on efface tous les fichiers contenus dans l'unité de liaison, on efface tous les fichiers associés à un titre comprenant un fichier spécifique à effacer, ou on n'efface que le fichier spécifique à effacer.
