String ^source = "C:/a.txt";
String ^destination = "C:/folder/a.txt";
      // Ensure that the target does not exist.
      File::Delete( destination );
      // Copy the file.
      File::Copy( source, destination );
      Console::WriteLine( "{0} copied to {1}", source, destination );
      // Try to copy the same file again, which should fail.
      File::Copy( source, destination );
      Console::WriteLine( "The second Copy operation succeeded, which was not expected." );
   catch ( Exception^ e )
      Console::WriteLine( "Double copying is not allowed, as expected." );
      Console::WriteLine( e );

http://msdn2.microsoft.com/en-us/library/system.io.directory.aspx includes an example (also uses .Exists to make sure it doesn't exist before creating it)

And moreover the second copy will also be succeeded bcoz you are not moving the file, just copying the file... Before deleting a file check whether the file exists else it will throw an exception


To make the directory creation common, since destination path may change use the following

               String ^destination = "C:/folder/a.txt";

               FileInfo^ finfo = gcnew FileInfo("C:/folder/a.txt");

                if (!Directory::Exists(finfo->Directory))

Sorry if any mistake in my code... I am a C# developer :(
