Description: 我经常在网上碰到同行请求开发文件系统驱动。windows的pc机上以过滤驱动居多。其目的不外乎有以下几种: 一是用于防病毒引擎。希望在系统读写文件的时候,捕获读写的数据内容,然后检测其中是否含有病毒代码。 二是用于加密文件系统,希望在文件写过程中对数据进行加密,在读的过程中进行解密。 三是设计透明的文件系统加速。读写磁盘的时候,合适的cache算法是可以大大提高磁盘的工作效率。windows本身的cache算法未必适合一些特殊的读写磁盘操作(如流媒体服务器上读流媒体文件)。设计自己的cache算法的效果,我已在工作中有所感受。 如果你刚好有以上此类的要求,你可以阅读本教程。-I often encounter online request peer file system driver development.

[Windows DevelopCacheSetSource

Description: CacheSet is an applet that allows you to manipulate the working-set parameters of the system file cache. Unlike CacheMan, CacheSet runs on all versions of NT and will work without modifications on new Service Pack releases. In addition to providing you the ability to control the minimum and maximum working set sizes, it also allows you to reset the Cache s working set, forcing it to grow as necessary from a minimal starting point. Also unlike CacheMan, changes made with CacheSet have an immediate effect on the size of the Cache. Full source code is included. -CacheSet is an applet that allows you to man ipulate the working-set parameters of the syst em file cache. Unlike CacheMan.

The primary platforms is Linux. It does not handle data in pull mode (File, HTTP and FTP) but uses RTSP/RTP (and Files). It uses RTSP as control protocol to communicate with possible streaming servers. The video data is transported via RTP. -The KOM (S) Streaming System provides a ser ver, a client, and a proxy cache for audio/video streaming.

[OS Developfat16

Description: 完成了一套基于FAT16,并只支持短路径名的函数包。 可用于虚拟磁盘建立。甚至你自己写操作系统,文件系统就可以直接使用他。 由于当初是为朋友在他的板子上跑,只有1K ram,还不能全用,最多只有600-700字节可使用, 所以没有采用缓存的形式,直接采用读写操作。 他可以很轻易的扩充到FAT32(甚至FAT12都可以给予支持),当然还只是支持短路径名。说实在 除了高级应用FAT系列的长文件名真是费事。 这里,我打算将其做成SpaceC的控件之一,用于整合资源文件。-Based on the completion of a set of FAT16, and only supports a short path name of the function package. Can be used for the establishment of a virtual disk. Or even write your own operating system, file system can be directly used on him. Because it was for a friend in his board on the run, only 1K ram, also should not use the whole, a maximum of only 600-700 bytes can be used, there is no form of the use of the cache, directly read and write operations. He can be easily expanded to FAT32 (or FAT12 can support), of course, only to support the short path name. To tell the truth, apart from advanced applications FAT series of long file name is really cumbersome. Here, I intend to make one of SpaceC control for integrated resource file.

[Driver Develop(OReilly)WindowsNT_FileSystemInternals_DevelopersG

Description: Rajeev Nagar著,O Reilly出版社出版。 本书重点在解释Windows NT的I/O子系统,缓存管理器,虚拟内存管理器的内部实现细节。特别地,它关注NT平台上文件系统驱动和过滤驱动的实现方式,这些都需要以上几个组件的支持。-Over the past three years, Windows NT has come to be regarded as a serious, stable, viable, and highly competitive alternative to most other commercially available operating systems. It is also one of the very few new commercially released operating systems that has been developed more or less from scratch in the last 15 years, and can claim to have achieved a significant amount of success. However, Microsoft has not yet documented, in any substantial manner, the guts of this increasingly important platform. This has resulted in a dearth of reliable information available on the internals of the Windows NT operating system. This book focuses on explaining the internals of the Windows NT I/O subsystem, the Windows NT Cache Manager, and the Windows NT Virtual Memory Manager. In particular, it focuses on file system driver and filter driver implementation for the Windows NT platform, which often requires detailed information about the above-mentioned components.

Also unlike CacheMan, changes made with CacheSet have an immediate effect on the size of the Cache. Use CacheSet to performance tune the system Cache size in a way not possible without tweaking internal variables the way CacheMan does. Note: To use CacheSet on NT 4.0 Service Pack 4 and later you must have the "Increase Quota" privilege (administrator accounts have this privilege by default). CacheSet has been updated to enable this privilege so that it works on SP4.

[Windows DevelopCache

Description: The Cache Manager is a software-only component that is tightly integrated with the Windows NT Memory Manager to integrate the caching of file system data with the Virtual Memory System. Some operating systems implement their file systems so they have a distinct data cache. However, because such caches must be managed from physical memory they are limited in size – and memory used for such a cache is not available for use elsewhere in the system.
