摘要： A method is provided for updating an application residing on a storage device of a computing device. The update is simulated by performing all necessary actions except for actually committing data relating to the update to the storage device, and it is determined whether the simulated update succeeded. If so, the update is performed by performing the same necessary actions and also actually committing the data relating to the update to the storage device.
摘要翻译：提供了一种用于更新驻留在计算设备的存储设备上的应用的方法。通过执行所有必要的操作来模拟更新，除了实际提交与存储设备的更新相关的数据，并且确定模拟更新是否成功。如果是这样，则通过执行相同的必要操作并且实际地向存储设备提交与更新有关的数据来执行更新。

摘要： Directories in a file system are defined with a dummy cluster in a file allocation table as the initial entry. Subsequent clusters in a directory's definition may define any data for the directory that can be changed in a transaction-safe mode. A directory may be modified in a transaction-safe mode by modifying any of the subsequent clusters while tracking changes in a second file allocation table. When the changes have been made to the directory, a pointer to the second file allocation table may be switched to indicate that the second file allocation table is now last known good. The first file allocation table may then be synchronized with the second.
摘要翻译：文件系统中的目录使用文件分配表中的虚拟集群作为初始条目进行定义。目录定义中的后续集群可以定义可以在事务安全模式下更改的目录的任何数据。可以通过在跟踪第二个文件分配表中的更改的同时修改任何后续集群来以事务安全模式修改目录。当对目录进行了更改时，可以切换指向第二文件分配表的指针，以指示第二文件分配表现在最后一个已知的。然后可以将第一文件分配表与第二文件分配表同步。

摘要： A transaction safe file system uses two sets of file allocation tables and bitmap images to perform file modifications on one of the sets while the other set remains a last known good set. After a modification is complete, a pointer is changed to the newly modified set, and the newly modified set becomes the last known good set. The sets are then synchronized. The file allocation table is used to define cluster chains while the bitmap image is used to determine if a cluster is free or not. In some operations, only the bitmap image may need to be manipulated. The file system may be used in a transaction safe mode as well as a non-transaction safe mode.
摘要翻译：交易安全文件系统使用两组文件分配表和位图图像来对其中一个集合执行文件修改，而另一个集合仍然是最后一个已知的好集合。修改完成后，指针将更改为新修改的集合，新修改的集合将成为最后一个已知的集合。然后将组同步。文件分配表用于定义集群链，同时位图图像用于确定集群是否空闲。在某些操作中，只能对位图图像进行操作。文件系统可以用于事务安全模式以及非事务安全模式。

摘要： The present invention provides an efficient application oriented security model. Prior to execution, an application is authenticated, and security information associated with the application is retrieved. The security information is then used to generate a token that is attached to the application. The security information may include a principle account associated with the application, a list of group accounts, and a corresponding privilege list.

摘要： In one aspect, the present disclosure describes a process for maintaining file allocation tables (FATs) for a volume of storage medium. The process includes triggering, by a write operation, modification of data in an existing sector of a data file by writing of data to a new sector of the storage medium. The process also includes writing revised used/unused sector information into one FAT and setting a variable indicative of a number of FATs (NOF) to a first value. The process additionally includes copying the one FAT to another FAT and re-setting the variable to a second value.

摘要： A computing device includes a storage device and a file system for storing and retrieving files on the storage device. The storage device includes storage space divided into sectors and the file system externally addresses the storage device on a per-sector basis, but internally divides each sector of the storage device into chunks and manages data within each sector on a per-chunk basis. Thus, the file system reads a chunk from or writes a chunk to the storage device by reading or writing the sector having the chunk.
摘要翻译：计算设备包括存储设备和用于在存储设备上存储和检索文件的文件系统。存储设备包括分为扇区的存储空间，并且文件系统以每个扇区为基础外部地存储存储设备，但是内部将存储设备的每个扇区划分成块，并且以每个块为基础管理每个扇区内的数据。因此，文件系统通过读取或写入具有该块的扇区来从存储设备读取块或将其写入存储设备。
