This book is a licensed reprint of the original content from "Windows NT File System Internals", by Rajeev Nagar, originally published by O'Reilly & Associates in 1998. As recently announced in The NT Insider, OSR purchased the publishing rights to this industry-recognized book, and is pleased to be able to make this reprint available to the Windows file system development community, under the new, OSR Press publishing label. The high level table of contents for this book is as follows: Windows NT System Components, File System Driver Development, Structured Driver Development, The I/O Manager, The NT Virtual Memory Manager, The NT Cache Manager (I, II, III), Writing A File System Driver (I, II, III), and Filter Drivers. Again, please note that the original contents of this book (circa 1998) have not been updated for this reprint. However, given the core file system interface in Windows has not drastically changed (like other driver models in Windows), this book is still valuable to the Windows file system and filter driver development community. OSR Press does have plans for updates to the original contents of this book, likely to be published under a new title. Stay tuned!
