QFile::copy won't work because _qsetsettings.fileName() "a system
registry path, not a file path". I don't think there is a way to do
this without copying the individual keys yourself, e.g.

#include <QtGui>

int main()
{
	QSettings input("ORG_NAME", "APP_NAME");
	QSettings output("./foo.ini", QSettings::IniFormat);
	QStringList keys = input.allKeys();

	foreach( QString key, keys )
	{
		output.setValue(key, input.value(key));
	}

	return 0;
}
