It's a bit further down the same file:

	int nUsed    = g.attribute("used" , "0" ).toInt();

	...

	os << "            <li>Space Used: ";
	sRep = c.toString(nUsed) + " MB";
	os << sRep << "</li>\r\n";

If it were me to avoid them getting out of sync I would move the >>10
and the naming of the units next to each other, by making the
attributed and nUsed and friends use bytes as the units, and doing the
shift in the latter bit of code right where the "MB" (or "GB") was
appended, but maybe that's just me and perhaps you are looking for the
smallest change to make.

Ian.
