    • A method includes defining a host capability; creating for a storage device a second directory tree from a first directory tree of the storage device that is included in a file system within the storage device; and, for a data file that is stored in the storage device and is selectable for consumption by a host through the first directory tree that is included in the storage device's file system, determining whether the data file requires for consumption a host having the defined host capability. If the data file requires a host having the defined host capability, an entry is created in the second directory tree in which the data file is not selectable for consumption by the host. Otherwise, an entry is created in the second directory tree in which the data file is selectable for consumption by the host. Subsequent to connecting the storage device to a host if the host has the defined capability the first directory tree of the storage device is used to present a view of the file system of the storage device to the host, and if the host does not have the defined capability the second directory tree is used to present a modified view of the file system to the host in which a data file not requiring the defined capability would be selectable for consumption by the host and in which a data file requiring the defined capability would not be selectable for consumption by the host.
    • 一种方法包括定义主机能力; 从存储设备中的文件系统中包括的存储设备的第一目录树中为存储设备创建第二目录树; 并且对于存储在存储装置中的数据文件,并且可被主机通过包含在存储装置的文件系统中的第一目录树选择供消费,确定数据文件是否需要消耗具有定义的主机的主机 能力。 如果数据文件需要具有定义的主机能力的主机,则在第二目录树中创建一个条目,其中数据文件不可供主机使用。 否则,在第二目录树中创建一个条目,其中数据文件可选择供主机使用。 如果主机具有定义的能力,则在将存储设备连接到主机之后,存储设备的第一目录树被用于向主机呈现存储设备的文件系统的视图,并且如果主机没有 定义的能力,第二目录树用于向主机呈现文件系统的修改视图,其中不需要定义的能力的数据文件将被主机可选择供消费,并且其中需要定义的能力的数据文件将不会 可选择供主机使用。
