Abstract

L'invention concerne un dispositif électronique comprenant : une mémoire pour stocker des instructions ; et un processeur connecté électriquement à la mémoire, les instructions, lorsqu'elles sont exécutées, permettant d'interroger des informations de temps de correction de répertoire d'un répertoire inclus dans une mémoire connectée au dispositif électronique lorsque le processeur est inclus dans le dispositif électronique ou qu'un processus de balayage pour la mémoire est exécuté, de sauter une interrogation pour des informations de temps de correction de fichier concernant un fichier enfant du répertoire lorsque les informations de temps de correction de répertoire correspondent à des informations de temps de correction de répertoire finales enregistrées dans une table de base de données, d'interroger les informations de temps de correction de fichier concernant le fichier enfant lorsque les informations de temps de correction de répertoire du répertoire ne correspondent pas à des informations de date de correction finales enregistrées dans la table de base de données, d'extraire des métadonnées concernant le fichier enfant de façon à les stocker dans la table de base de données lorsque les informations de temps de correction de fichier ne correspondent pas aux informations de temps de correction de fichier finales enregistrées dans la table de base de données et d'interroger des informations de temps de correction de répertoire concernant un répertoire enfant du répertoire. Divers autres modes de réalisation de l'invention identifiés dans la description sont également possibles.
