The present invention is directed at a system and method for managing and evicting objects stored in a cache. The invention provides a mechanism for determining which objects to evict based on a weight that is calculated for each object stored in the cache. The weight is determined by at least two factors, including file size, file type, primary user, last access time, and the like, and by the relative importance of each of the factors. The weight for each object may be determined autonomously and/or may be determined upon a trigger event. The factors and their relative importance may be obtained from a policy applicable to one or several computers.

A data presentation system dynamically generates and renders a user interface (UI) in the form of a Hypertext Markup Language (HTML) document. Extensible Markup Language (XML) data files contain data that defines the UI. The XML data is maintained independently of any application and/or computing system's settings and controls that define the presentation of the UI. The XML data files also have reference links to secondary data files that contain data further defining the UI. The UI is dynamically generated when an application invokes the XML data files. The HTML document incorporates the data from both the XML data files and from the secondary data files when rendering the UI.

Described is a system and method that facilitates fast and reliable synchronization of computer/file system directories. A synchronization (FastSync) subsystem operates in a discovery/enumeration phase to provide a calling client with a set of the differences between directories, and then operates in an action phase to perform operations as directed by the client to synchronize the different directories. The discovery/enumeration and action phases use parallel operation and I/O (input/output) pipelining. Multiple threads are used during enumeration to enumerate each directory's children, and enqueues each sub-directory to be handled by a new thread. During the action phase, when an operation is requested, the FastSync subsystem packages up the operation, item pointer, and context information into an internal context block and queues that packet as a work item for a process thread pool to handle.

Described is a system and method that synchronizes cached files and directories with a server's files and directories via a layered architecture, by collapsing state information into an index into a fixed set of known states, and looking up the action that synchronizes that state. The actions are then taken to synchronize the content. Any of fifty possible synchronization states are thus handled. A synchronization controller requests a subsystem to evaluate a local cache and remote file system to generate state flags for each item considered for synchronization. The synchronization controller processes the state information to identify a selected table from among a plurality of tables that contain the fifty values, and uses other flags to compute an index into the table. The selected table contains values that index into an action table containing actions that specify an operation set that is requested to synchronize the particular state scenario.

The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e. g. , client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

Aspects of the subject matter described herein relate to synchronizing for directory actions performed while offline. In aspects, file system objects that reside on a remote data store are made available for offline use. While offline, a client receives an indication that a directory is to be deleted or renamed. In response, the client modifies its local copy of the directory and its descendants if any and stores one or more tombstones that include information that the client can use when synchronizing the changes made to the directory when the client is reconnected to the remote data store. When the client reconnects to the remote data store, the client synchronizes changes made while offline with the remote data store. Resolution conflict mechanisms may be used during this synchronization.

A system and method for implementing a consistent user name-space on networked computing devices is provided. When a network connection between a local or host computing device and one or more remote computing devices is present, remote items are represented using the same methodology as items located on the host computing device. To the user, remote and local items are indistinguishable. When the network connection is lost or items located on a remote computer are otherwise unavailable, the unavailable items remain represented on the host computing device. Unavailable items are represented in a way that informs the user that the items may not be fully accessed.
