摘要： A computing device includes a storage device having a file and a file system for storing and retrieving the file on the storage device. The file includes a plurality of segments, where each of at least some of the segments is null data and each of at least some of the segments is substantive data. The file has space allocated therein for each null data segment but such allocated space is not actually filled with information, and the file has space allocated therein for each substantive data segment and such allocated space is actually filled with information. Each null data segment is not actually physically stored on the storage device and each substantive data segment is actually stored on the storage device.

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： 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 flash driver can be used by file systems and other applications to determine more detailed attributes and properties, such as region geometry, that describe the underlying flash component. This allows a file system, for example, to be made aware of each flash region and its properties. The file system may then be optimized to more efficiently utilize the flash component. These optimizations may lead to increased component longevity and better read/write performance.
