A really secure folder lock program?

I am looking for a program that can lock folders, and in case if my laptop is stolen and C drive reformatted and reinstalled, and my locked folders are on D drive, these folders to remain unaccessible. Also, these folders to remain unaccessible if someone try to use live linux distros from USB drive.

Is there such a program?

I tested Folder Lock from NewSoftwares, but when you uninstall the program the locked folders become visible and accessible.

 

Encryption and steganography. I recommend TrueCrypt and OpenPuff.

 

Thanks, i will try these two programs.
