数据更新系统及计算机程序
摘要：
提供了一种即使在更新导航设备的存储介质的大量数据时也能够在短时间内容易地执行更新处理的技术。生成了与存储介质的分区结构相对应的目录结构。生成用于分区HDn(n＝0，1，2，4，6)内的已更新的数据内容的镜像文件IF。生成的分区HDn的镜像文件IF存储在生成的目录结构中与分区HDn相对应的目录DIR内。从与分区HDn相对应的目录DIR读出的镜像文件IF的数据内容写入存储介质的分区HDn中。
摘要（英）：

Art is provided that is capable of easily performing update processing in a short time even when updating numerous data of a storage medium of a navigation device. A directory structure corresponding to a partition structure of a storage medium is created. Image files IF are generated for updated data content within partitions HDn (n=0, 1, 2, 4, 6). The generated image files IF of the partitions HDn are stored in directories DIR that correspond to the partitions HDn in the created directory structure. Data content of the image files IF read from the directories DIR that correspond to the partitions HDn is written to the partitions HDn of the storage medium.
