Copying a file to a directory that might not be writable by the application.

Question

I am writing an application and I am at this point at the workflow:

-File A doesn't exist?
 -Copy file B to file A
  -Error?
   -Copy file B to file A with higher privileges

I have totally no idea where to start, can someone help me out? Thanks! :D
