AFAIK it is not possible to create the file and the directory directly with QFile. You have to first create the directory (QDir::mkpath will create the full path) and then the file (QFile::open).

QString path("SomePath/NewDirectoryA/");
QDir dir; // Initialize to the desired dir if 'path' is relative
          // By default the program's working directory "." is used.

// We create the directory if needed
if (!dir.exists(path))
    dir.mkpath(path); // You can check the success if needed

QFile file(path + "NewFile.kml");
file.open(QIODevice::WriteOnly); // Or QIODevice::ReadWrite
