Driver code? Which language - C++ or C# ?

Not Visual C++, just C++. PathFileExist() is a Shell function and you cannot use such calls in driver code. What exactly are you trying to get your driver code to do?

Why are you doing this in driver level code? What type of driver is this and why does it need to create a file?

If you're working at a driver level, why not do a C-style fopen() and see if the file exists in that manner? If it doesn't, the fopen() will fail and return NULL.
