File System Filter Driver Is Not Loaded

This tutorial provides you with easy to understand steps for a simple file system filter driver development. The demo driver that we show you how to create prints names of open files to debug output. This article is written for engineers with basic Windows device driver development experience as well as knowledge of C/C++. In addition, it could also be useful for people without a deep understanding of Windows driver development. Written by: Sergey Podobriy, Leader of Driver Team Contents What is Windows file system filter driver? A Windows file system filter driver is called during each file system I/O operation (create, read, write, rename, etc.). Therefore, it is able to modify the behavior of the file system.

File system filter drivers are comparable to legacy drivers, although they require several special development steps. Security, backup, snapshot, and anti-viruse software uses such drivers. Developing a Simple File System Filter Driver Before starting development First, in order to develop a file system filter driver, you need the IFS or WDK kit from. You also have to set the%WINDDK% environment variable to the path, where you have installed the WDK/IFS kit. Attention: Even the smallest error in a file system driver can cause BSOD or system instability.

Main.c File system filter driver entry It is an access point for any driver, including for file system filter driver. The first thing we should do is store DriverObject as a global variable (we'll use it later). // Macro to test if FAST_IO_DISPATCH handling routine is valid #define VALID_FAST_IO_DISPATCH_HANDLER(_FastIoDispatchPtr, _FieldName) (((_FastIoDispatchPtr)!= NULL) && (((_FastIoDispatchPtr)->SizeOfFastIoDispatch) >= (FIELD_OFFSET(FAST_IO_DISPATCH, _FieldName) + sizeof(void *))) && ((_FastIoDispatchPtr)->_FieldName!= NULL)) Fast I/O pass-through Unlike IRP requests, passing through fast-IO requests requires a huge amount of code because each fast I/O function has its own set of parameters. Below you can find an example of a common pass-through function.
