摘要： In accordance with one or more aspects, one or more portions of each of multiple files that have been freed are determined. One or more delete notifications are generated identifying the one or more portions of the multiple files. Each portion is identified as a range of data on a storage device, and each delete notification includes one or more ranges of data on the storage device. These generated delete notifications are then sent to a storage stack. Additionally, an application can determine that one or more ranges of data of a storage device are to be freed and send a delete notification, in the absence of a file system on the device, to the storage stack identifying the one or more ranges of data of the storage device that are to be freed.

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： A storage stack delete notification can be received at a storage stack filter. The delete notification can indicate deletion of primary data in a primary storage region. Secondary data that is taking up storage resources managed by the storage stack filter can be identified. The secondary data can be associated with the primary storage region, and the storage resources can be resources other than the primary storage region. It can be determined whether it is useful to have the secondary data continue taking up the storage resources. If having the secondary data continue taking up the storage resources is not useful, then the storage resources can be freed.
摘要翻译： 可以在存储堆栈过滤器处接收存储堆栈删除通知。 删除通知可以指示删除主存储区域中的主数据。 可以识别占用存储堆栈过滤器管理的存储资源的次要数据。 辅助数据可以与主存储区域相关联，并且存储资源可以是除主存储区域之外的资源。 可以确定辅助数据是否继续占用存储资源是否有用。 如果继续占用存储资源的次要数据是没有用的，则可以释放存储资源。

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 volume. If the delete notification does not apply to the entire storage volume, 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 volume, a second set of actions can be taken with the storage stack filter in response to the delete notification.

摘要： An extensible file system format for portable storage media is provided. The extensible file system format includes the specification of primary and secondary directory entry types that may be custom defined. The primary and secondary directory entry types can be further classified as critical and benign directory entries.

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.
摘要翻译： 实施例包括文件系统数据结构和文件系统识别API，其可以允许操作系统将存储设备的分区识别为具有有效的文件系统，即使操作系统不知道如何先前访问文件系统。 文件系统可以在存储设备上的分区内的标准化的已知位置中实现这些数据结构，使得操作系统可以使用API或其他功能来检查这些数据结构的存在的已知位置。 关于如何解释数据结构的信息可以使用网络或其他来源获得。

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.
摘要翻译： 应用程序编程接口（API）模块提供对数据的访问，与非特权用户模式中的文件系统实现无关。 具有由操作系统可识别的文件系统的发现卷具有防止对存储在不可识别的主卷中的数据的损坏的封面文件。 发现卷还包括可用于以非特权用户模式执行的数据访问API，以使操作系统可访问的主卷可能会找到主卷不可识别。
