摘要： A ghosting filter on a computing device perceives that a file is in a ghosted form and commands a file system of the device to retrieve ghosting information from the ghosted file. The ghosting filter receives a read command from an application on the device with respect to a portion of the data of the ghosted file. The read command has parameters including an offset into the portion of the data and a read length with respect to such portion. The ghosting filter initiates reconstituting of the portion of the data of the ghosted file based on the received ghosting information and data of the ghosted file at an alternate location, and after the portion of the data of the ghosted file has been reconstituted responds to the read command with the portion of the data requested.
摘要翻译：计算设备上的重影过滤器感知文件是重影形式，并命令设备的文件系统从重影文件中检索重影信息。重影过滤器相对于重影文件的一部分数据从设备上的应用接收读取命令。读取命令具有包括对数据部分的偏移量和相对于这些部分的读取长度的参数。重影过滤器基于所接收的重影信息和重置文件在备用位置的数据重新构建重影文件的部分数据，并且在重影文件的部分数据被重构之后响应于读取命令与所请求的数据的部分。

摘要： A ghosting filter on a computing device receives a read command for a requested range of data of a ghosted file. The requested range is categorized into first segments present in the ghosted file, second segments pending to be reconstituted from an alternate location to the ghosted file, and third segments that are not first or second segments. Reconstitution of any third segments is initiated to convert same to second, pending segments, and the read command is responded to with the requested range of the data once all second segments are in fact reconstituted from the alternate location to the ghosted file and thus converted to first, pending segments.
摘要翻译：计算设备上的重影过滤器接收对所请求的重影文件数据范围的读命令。所请求的范围被分类为存在于重影文件中的第一段，等待从备用位置复制到重影文件的第二段，以及不是第一或第二段的第三段。启动任何第三段的重构以将其转换为第二待处理段，并且一旦所有第二段实际上从备用位置重构到重影文件，并且读取命令响应于所请求的数据范围，并因此转换为第一，待处理段。

摘要： Files on a computing device are defined to include data and metadata relating to the data. Data from each file has been removed therefrom and stored at an alternate location and the file is in a reduced, ghosted form. Each of at least some ghosted files has been fully or partially reconstituted for use by retrieving the data thereof from the alternate location and associating such retrieved data with such ghosted file to form the reconstituted file. Upon receiving a trigger based on a triggering event, files are selected from among the fully and partially reconstituted files and never-ghosted files based on first predetermined selection criteria, and each of at least some of the selected files are re-ghosted.
摘要翻译：计算设备上的文件被定义为包括与数据相关的数据和元数据。来自每个文件的数据已从其中移除并存储在备用位置，并且该文件处于缩小的重影形式。至少一些重影文件中的每一个已经被完全或部分地重构，以便通过从备用位置检索其数据并将这些检索的数据与这样的重影文件相关联以形成重构文件。在基于触发事件接收到触发时，基于第一预定选择标准从全部和部分重构的文件和从未重影的文件中选择文件，并且至少一些所选择的文件中的每一个被重新设置。

摘要： A computing device has a storage volume, a file system managing the storage volume, and a file stored on the storage volume and accessed by such file system. The file system receives an open command for the file from an application, notes that the file has been ghosted in that data of the file has been moved to an alternate location, and returns an error. The returned error is intercepted and the file system is commanded to retrieve ghosting information from the ghosted file. A handle corresponding to the ghosted file is delivered to the application, and a read command for the file is received from the application, including the handle, an offset, and a read length. Reconstituting of the ghosted file is initiated based on the data thereof at the alternate location, and after reconstituting the read command is responded to with the data requested.

摘要： A computing device has a file stored on a storage volume by a file system and accessed through such file system. The file is defined to include data and metadata relating to the data, and at least a portion of the data of the file is removed from the file and stored at an alternate location such that the data does not occupy substantially any space on the volume and the file is in a reduced, ghosted form. The ghosted file is reconstituted for use by retrieving the data from the alternate location and associating such retrieved data with such ghosted file to form the reconstituted file.

摘要： To reconstitute a ghosted file for use, a single ghosting filter on a computing device locates ghosting information in the metadata of the ghosted file and locates within the ghosting information an identification of a particular ghosting manager of the computing device, where the identified ghosting manager is responsible for the ghosted file. Thereafter, the ghosting filter communicates to the identified ghosting manager a request to obtain data of the ghosted file from a corresponding alternate location, and the identified ghosting manager does in fact obtain such requested data from such alternate location. Upon receiving the requested data of the ghosted file from the identified ghosting manager, then, the ghosting filter reconstitutes the received data to the ghosted file. The single ghosting filter is generic to all of the ghosting managers of the computing device.

摘要： A method and system for verifying the integrity of a storage volume. When volume verification is desired, a shadow copy of the volume is created. A verification tool operates on the shadow copy and provides a report that indicates if any errors are found in the shadow copy. If errors are found on the shadow copy, this indicates that the same errors likely still exist on the live volume. In the event of errors, a system administrator or the like may take the live volume off-line and fix the errors found.

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. The directory entry types can define whether a cluster chain corresponding to a file can be contiguously allocated.

摘要： A file system which is enabled to use a Metadata Partition instead of VAT for write-once discs, is provided by a pseudo-overwrite method. On applying this invention to a drive apparatus which supports pseudo-overwrite media, the file system distinguishes data to overwrite from data to append. When the data is newly written to a logical sector (S1305), the drive apparatus writes the data to a physical sector to which the logical sector corresponds (S1311). When the logical sector is overwritten the data is written to another unrecorded physical sector in the volume space (1321), and remapping information that specifies the original address, and the remapping address are stored in the remapping table (S1322).
摘要翻译：通过伪重写方法提供了能够使用元数据分区而不是VAT一次写入光盘的文件系统。在将本发明应用于支持伪覆盖介质的驱动装置时，文件系统将数据区分为从附加到数据的覆盖。当数据被新写入逻辑扇区时（S1305），驱动装置将数据写入与逻辑扇区对应的物理扇区（S1311）。当逻辑扇区被覆盖时，数据被写入卷空间中的另一个未记录的物理扇区（1321），并且重映射指定原始地址的信息和重映射地址被存储在重映射表中（S1322）。

摘要： A method and system for maintaining namespace consistency between selected objects maintained by a file system and a filter associated therewith. A filter monitors selected types of requests (or operations associated therewith) and determines whether the object is within a namespace associated with the filter. The namespace associated with the filter is updated based on a change to the object.
