Is it possible to get a full path with double backslash by using Path.GetFullPath? Something like this:
C:\\\\Users\\\\Mammamia\\\\Videos\\\\Doc
I would recommend doing a String.replace(). I recently had to do this in a project for myself. So if you do something similar to:
String input = Path.GetFullPath(x);
input = input.Replace("\\","\\\\");
I am fairly confident that is what you need :)
