File system filter driver

[mayuradatia]

1) I want to encrypt all my .doc files before saving and decrypt before opening so that they open fine in Word. Should I be writing a file system filter driver for such a task? Is there any other way, I can do this?

2) Can I use WDK to build such a file system filter driver?

3) Do I need to use IFS kit for writing a file system filter driver?

4) Will one filter driver work across various file systems supported by Windows XP & Vista?

5) Will a new file system filter driver work fine on the machine having anti-virus software installed.
