Abstract

La présente invention porte sur la synchronisation de la position d'utilisation dans un fichier entre une pluralité d'ordinateurs. Un ordinateur reçoit d'un autre ordinateur, conjointement à un premier fichier, une première information de position d'utilisation indiquant la position d'utilisation par une première application exécutée sur l'autre ordinateur dans un premier fichier, et à partir de ce premier fichier et de ladite première information de position d'utilisation, affiche le premier fichier dans une seconde application qui peut traiter le premier fichier de manière à faire correspondre la position d'utilisation à la première information de position d'utilisation.
