I want to create a file system filter driver, which will encrypt the data while writing to disk and will decrypt the data while reading. (I hope one needs to use IRP_MJ_WRITE and IRP_MJ_READ)<br />
<br />
OS: Windows XP<br />
I've the DDK/IFS kit.<br />
<br />
I'm modifying the example of SFilter in IFS kit. I want this file sytem filter driver to work only for Floppy drive.<br />
<br />
Any example source code, pointers to specific documents will be helpful.<br />

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
