Abstract

Les modes de réalisation de la présente demande concernent un procédé et un appareil de fonctionnement de fichier, un dispositif informatique et un support de stockage lisible par ordinateur. Le procédé de fonctionnement est appliqué au noyau d'un dispositif informatique, et consiste à : obtenir une commande de déplacement liée à un fichier ; accéder, selon la commande de déplacement, à un espace de stockage dans lequel se trouve le fichier, dans un module de stockage local du dispositif informatique ; déplacer le fichier, du module de stockage local vers un module de stockage en nuage ; et écrire une étiquette de déplacement du fichier dans le module de stockage local, l'étiquette de déplacement étant utilisée pour permettre au noyau d'exécuter une opération ultérieure sur le fichier. Au moyen de la solution technique, le noyau du dispositif informatique peut déplacer le fichier, du module de stockage local vers le module de stockage en nuage ; ainsi, l'espace de stockage dans le module de stockage local est économisé et la capacité de stockage du dispositif informatique est améliorée, ce qui assure que le module de stockage local a suffisamment d'espace de stockage restant, permet d'éviter de provoquer des saccades du dispositif informatique et améliore ainsi l'expérience d'utilisateur sur le dispositif informatique.
