摘要： Access to WebDAV (Distributed Authoring and Versioning) servers is provided in a manner that is essentially transparent to applications. A WebDAV redirector and related components support file system I/O requests and network requests directed to WebDAV servers identified by URI (Universal Resource Identifier) names, or by a drive may be mapped to a WebDAV share. An application's create or open I/O requests directed to a WebDAV server are detected, and result in a local copy of the file being downloaded and cached for local access. When closed, the local file is uploaded to the WebDAV server. Network-related requests such as for browsing that are directed to a WebDAV server are also handled transparently. WebDAV files may be locally encrypted and decrypted at the file system level, transparent to applications and the WebDAV server, via an encrypting file system that performs local encryption and decryption at the local file system level.
摘要翻译：以对应用程序基本透明的方式提供对WebDAV（分布式创作和版本控制）服务器的访问。 WebDAV重定向器和相关组件支持文件系统I / O请求和针对由URI（通用资源标识符）名称标识的WebDAV服务器的网络请求，或者由驱动器映射到WebDAV共享。检测到应用程序创建或打开指向WebDAV服务器的I / O请求，并导致要下载并缓存的文件的本地副本以进行本地访问。关闭时，本地文件上传到WebDAV服务器。与WebDAV服务器相关的网络相关请求（如用于浏览）也被透明处理。可以通过在本地文件系统级执行本地加密和解密的加密文件系统，在文件系统级别对WebDAV文件进行本地加密和解密，对应用程序和WebDAV服务器是透明的。

摘要： A method of purging cached open files from a client-side delayed close list on a remote file system. The remote file system stores a unique file identifier for each cached open file which is independent of the cached file's namespace. In response to a delete or rename command of a remote target file, the remote file system obtains a target file identifier from the target file's server. The remote file system then compares the target file identifier with each of the cached file's unique file identifier. If a cached file's unique file identifier matches the target file identifier, the cached file is purged from the delayed close list.
摘要翻译：从远程文件系统上的客户端延迟关闭列表中清除缓存的打开文件的方法。远程文件系统为每个缓存的打开文件存储唯一的文件标识符，该文件独立于缓存文件的命名空间。响应于远程目标文件的删除或重命名命令，远程文件系统从目标文件的服务器获取目标文件标识符。然后，远程文件系统将目标文件标识符与每个缓存文件的唯一文件标识符进行比较。如果缓存文件的唯一文件标识符与目标文件标识符匹配，则缓存文件将从延迟关闭列表中清除。

摘要： An improved method and system for client-side caching that transparently caches suitable network files for offline use. A cache mechanism in a network redirector transparently intercepts requests to access server files, and if the requested file is locally cached, satisfies the request from the cache when possible. Otherwise the cache mechanism creates a local cache file and satisfies the request from the server, and also fills in a sparse cached file as reads for data in ranges that are missing in the cached file are requested and received from the server. A background process also fills in local files that are sparse, using the existing handle of already open server files, or opening, reading from and closing other server files. Security is also provided by maintaining security information received from the server for files that are in the cache, and using that security information to determine access to the file when offline.
摘要翻译：用于客户端缓存的改进方法和系统，可透明缓存合适的网络文件以供离线使用。网络重定向器中的缓存机制透明地拦截访问服务器文件的请求，如果请求的文件被本地缓存，则尽可能满足缓存的请求。否则，缓存机制将创建本地缓存文件并满足来自服务器的请求，并且还将稀疏缓存文件填充为从服务器请求和接收的高速缓存文件中缺少的范围内的数据读取。后台进程还使用已经打开的服务器文件的现有句柄或打开，读取和关闭其他服务器文件来填充稀疏的本地文件。还通过维护从服务器接收到的缓存中的文件的安全信息来提供安全性，并使用该安全信息来确定在脱机时对文件的访问。

摘要： A system and method that automatically and transparently enable access to prior file or folder versions for a selected file or folder. When a file or folder is selected for version location, such as via a user interface, prior versions are automatically located and time data (e.g., determined from timestamps) identifying each of the prior versions is displayed. The user can then select a prior version for restoration and thereby recover from changed file data. The present invention can be implemented using remote file servers, or with local file system volumes. Prior to displaying the versions for selection, attributes of the prior versions may be requested, whereby only versions that actually exist can be displayed, and/or only versions with possibly different data are displayed, reducing unnecessary selection for restoration.

摘要： A method and system of recognizing words from handwritten symbols that are recognized by a computer recognizer. The recognizer produces a set of one or more alternatives for each symbol and orders the alternatives within each set in terms of the probability that each alternative matches the handwritten symbol for the set. A sequence of strings, each string having one alternative from each set, is enumerated. The enumerating proceeds in order such that the most probable alternatives from each set are used before the lower probability alternatives. Preferably, each string enumerated is looked up in a computer dictionary before enumerating other strings. If the string is found in the dictionary, the string is displayed, and preferably further enumerating stops. In an alternative embodiment, plural strings are enumerated before looking up a string in the dictionary. In another embodiment, plural strings are displayed before stopping further enumeration. Amended symbols may be used to change individual characters within a previously recognized word. A set of alternatives for each amended symbol is coupled with the unchanged symbols before enumerating strings and looking the strings up in a dictionary.

摘要： A system to perform transacted remote file operations over a network includes a client and a server. The client and server each include a transaction manager (TM) and a file system (FS). The client also includes a redirector (RDR), while the server includes a server application (SRV). The RDR receives a request for a remote transacted file operation. In response, the RDR retrieves the transaction from the request. The RDR may use the TM to marshall the transaction for transmission to the server. The RDR sends the transaction to the server over the network. The SRV component receives the transaction, which the TM and FS of the server then use to perform the file operation. The server then returns the file operation result to the client via the network.

摘要： A method and system for showing file system structures on a computer system that can be connected to multiple types of networks. The file shadowing mechanism automatically and transparently stores shadow copies of remote file system structures when they are accessed by a computer. The shadow copies of the file system structures are stored within a shadow database that resides within local memory of the computer. When the computer becomes disconnected from a network, shadow copies of file system structures for the network are used to service requests to access such file system structures.
