    摘要： A delete notification can be received at a storage stack filter in a storage stack. It can be determined whether the delete notification applies to an entire storage device. If the delete notification does not apply to the entire storage device, a first set of actions can be taken with the storage stack filter in response to the delete notification. If the delete notification does apply to the entire storage device, a second set of actions can be taken with the storage stack filter in response to the delete notification.

    摘要： Embodiments include a file system data structure and file system recognition APIs that may allow an operating system to identify a partition of a storage device as having a valid file system, even if the operating system does not know how to access the file system a priori. File systems can implement these data structures in a standardized, known location within a partition on the storage device such that an operating system may use APIs or other functions to examine the known location for the presence of these data structures. Information on how to interpret the data structure may be obtained using a network or other source.

    摘要： An application programming interface (API) module provides access to data, independent of filesystem implementation in a non-privileged user mode. A discovery volume having a filesystem recognizable by an operating system has cover files which prevent damage to data stored in an unrecognizable primary volume. The discovery volume also includes a data access API available for execution in a non-privileged user mode to render the primary volume accessible by operating systems which would otherwise find the primary volume unrecognizable.

    摘要： Described is a mechanism comprising a data screening filter and user mode service that applies (enforces) policies regarding allowing or blocking file content of a directory, based on matching the filename against patterns associated with that directory. An administrator configures a screening policy, such as the types of files to allow in a particular directory and the types of files to block. File groups of member patterns and non-member exclusion patterns are defined and selectively collected in directory screening objects (DSOs). A directory screening object (DSO) is associated with a directory. When an I/O create request specifying a filename and a target directory is received, the filename is evaluated against the member/non-member patterns in the file groups referenced by the DSO for that directory to make for an allow or block policy decision. If not matched, DSOs on parent directories are evaluated upwards seeking a policy decision.

    摘要： The recording method of the present invention includes the steps of: receiving a write instruction which specifies at least a logical sector in which data is to be written; determining whether the logical sector corresponds to a recorded physical sector or an unrecorded physical sector; when it is determined that the logical sector corresponds to an unrecorded physical sector, writing the data into the unrecorded physical sector, determining whether a verification of the data which has been written into a physical sector is successful, if the verification of the data that has been written is not successful, writing the data into an unrecorded physical sector, generating a remapping table including remapping information which remaps an original address of the physical sector corresponding to the logical sector to a remapping address of the selected physical sector, and writing the remapping table on the write-once disc.

    摘要： Disclosed is a method for creating and reading a contiguous file in an extensible file system. During the creation of a file on the storage media, the file system format check the bitmap to determine if there are areas of free space on the media that would permit the storage of the file in a contiguous manner. By storing the file in a contiguous manner the file may later be read without resorting to the file allocation table, because the file itself would not be fragmented on the storage media. Once an area of free space has been identified, the file is written to the media in a contiguous manner. Further, an associated entry for the file in the directory entry is updated or created to indicate that the file is a contiguous file and also provides basic parameters necessary to read the file without resorting to accessing the file allocation table.

    摘要翻译： 公开了一种在可扩展文件系统中创建和读取连续文件的方法。 在存储介质上创建文件期间，文件系统格式检查位图，以确定介质上是否存在允许以连续方式存储文件的可用空间区域。 通过以连续的方式存储文件，可以稍后在不依赖于文件分配表的情况下读取文件，因为文件本身不会在存储介质上分段。 一旦确定了可用空间区域，文件将以连续的方式写入介质。 此外，更新或创建目录条目中的文件的相关条目以指示文件是连续文件，并且还提供读取文件所必需的基本参数，而无需访问文件分配表。
