摘要

In a file system configured by one or a plurality of volumes, policy attribute data is set in correspondence with the path information of a directory, and a file is managed based on the policy attribute data. As a result, a policy specific to the directory can be set while maintaining the compatibility with an existing file system. For example, a volume number is set as the policy attribute data of a file, so that a file system administrator can specify the storage location of the file.
