An client-side performance optimization system for streamed applications provides several approaches for fulfilling client-side application code and data file requests for streamed applications. A streaming file system or file driver is installed on the client system that receives and fulfills application code and data requests from a persistent cache or the streaming application server. The client or the server can initiate the prefetching of application code and data to improve interactive application performance. A client-to-client communication mechanism allows local application customization to travel from one client machine to another without involving server communication. Applications are patched or upgraded via a change in the root directory for that application. The client can be notified of application upgrades by the server which can be marked as mandatory, in which case the client will force the application to be upgraded. The server broadcasts an application program's code and data and any client that is interested in that particular application program stores the broadcasted code and data for later use.

A web based application having non-file system structures is copied or archived by first initializing a file to store the web based application, including creation of a root directory within the file. Then, data directories are created under the root directory, and a number of storage data objects under the data directories are initialized for all non-file system structures of the web based application. Thereafter, the non-file system structures are copied and stored into the storage data objects. In embodiments where the web based application further includes files that are part of a file system, the files are stored as additional storage data objects under the root directory. Accordingly, database and operating system independence is achieved.

The present invention relates to a fine-granularity files and directory edition management method based on snapshots, belonging to the multi-version document system field. The present invention separates a name space consisting of files and dirnames in a whole file system from an edition space representing the generating periods of different editions, and adopts relatively independent strategies to execute management, forming a hierarchical two-dimensional structure, i.e. forming a hierarchical structure from a root directory to a file in the name space; in the edition space, the editions of files and directory are organized through an index structure chronologically, forming a hierarchical structure in the edition space. The retrieval of the name space adopts an index strategy based on dynamic hash. The retrieval of the edition space adopts an index strategy based on a red-black tree. The directory edition and file edition respectively adopt a red-black tree structure variant aiming at the respective characteristics. The present invention can greatly improve the usability and the performance of the system, and controls the amount of consumption of time and space resulting from the maintenance of historical editions in an acceptable scope.

Servers in a storage system store a nested multilayer directory structure, and a global index that is an abstract of the directory structure. The global index identifies respective portions of the directory structure that are stored in respective ones of the servers, and the global index identifies paths through the directory structure linking the respective portions. Upon performing a top-down search of the directory structure in response to a client request and finding that a portion of it is offline, the global index is searched to discover portions of the directory structure that are located below the offline portion. The global index may also identify the respective server storing each of the respective portions of the directory structure, and may indicate whether or not each of the respective portions of the directory structure is known to be offline.

A mobile wireless device programmed with a file system which is partitioned into multiple root directories. The partitioning of the file system ‘cages’ processes as it prevents them from seeing any files they should not have access to. A Trusted Computing Base verifies whether or not a process has the required privileges or capabilities to access root sub-trees. The particular directory a file is placed into automatically determines its accessibility to different processes—i.e. a process can only access files in certain root directories. This is a light weight approach since there is no need for a process to interrogate an access control list associated with a file to determine its access rights over the file—the location of the file taken in conjunction with the access capabilities of a process intrinsically define the accessibility of the file to the process. Another aspect of this invention is that each process can have its own private area of the file system guaranteeing confidentiality and integrity to its data.

A memory storage device, a memory controller thereof, and a method for automatically creating a fill-file thereof are provided. In the present method, a plurality of logical addresses is configured and grouped into a plurality of logical blocks to be mapped to physical blocks of a memory chip in the memory storage device. When a host system is powered on, whether the logical addresses have been formatted into a partition is determined. If the logical addresses have been formatted into a partition, whether a fill-file of a predetermined file capacity exists is determined. If the fill-file does not exist, data related to the fill-file is respectively filled into a file allocation table (FAT) and a root directory of the formatted partition when the host system reads the FAT and the root directory, so as to automatically create the fill-file.
