Solution is quite easy in your situation; just use this code:

var rootAppender = ((Hierarchy)LogManager.GetRepository())
                                         .Root.Appenders.OfType<FileAppender>()
                                         .FirstOrDefault();

string filename = rootAppender != null ? rootAppender.File : string.Empty;
