i am guess the problem is with the use of "My computer" in your drive path. The nokia should have a drive letter designated with it and this should allow you to access it like any other drive, like "C:\", not "My computer\\C:\\" as I am guessing you are doing right now in your code! As to what drive letter gets assigned to the nokia drive, I am not sure how you determine this at runtime with your application, so first step would be to get something hard-coded working =)
