We are developing a MiniFilter driver for encryption/decryption software. Since the software is supposed to run on Microsoft Vista, we are creating a MiniFilter driver rather then a full filter driver. The MiniFilter driver catches I/O calls and encrypts or decrypts data on the fly. We are capturing IRP_MJ calls from FilterManager and then taking necessary actions on the IO.
We are facing few issues in this and I am looking for suitable help. Also we are not sure how to handle memory mapped files.

Abhishek
