Real-time co-authoring of files on computing devices
A recently granted patent (Publication Number: US12001401B2) discloses a computing device with a unique method for synchronizing files. The device includes computer-readable storage media, processors, and an application with program instructions. These instructions enable the device to receive a file open request, synchronize a local copy with a hosted copy using a sync engine, open a temporary copy, connect to a co-authoring service, receive user edits, synchronize the temporary copy with the hosted file, and close the temporary copy without syncing the local copy. The patent also covers saving the temporary copy to persistent storage, deleting it from system memory, and efficiently updating chunk identifiers during synchronization.
Furthermore, the patent extends to a method for synchronizing file copies on a computing device. This method involves opening a temporary copy, establishing a connection to a co-authoring service, receiving user edits, and synchronizing the temporary copy with the hosted file. Upon closing the file, the method includes saving to persistent storage, opening from the storage location, and deleting from system memory. The synchronization process includes identifying base and updated states, determining delta chunks, and sending updates to the co-authoring service. Additionally, an initial synchronization request is made to ensure accurate updates based on chunk identifiers, enhancing the efficiency of file synchronization processes. Overall, the patent details a comprehensive system and method for efficient file synchronization on computing devices.
