I downloaded The upgrade only zip file and unzipped it. It did not make a 1.5.9 folder only a upload folder. I created a folder named Test and pasted the zip file there. Unzipped it. There is no 1.5.9 folder and in it the Upload folder. For testing purpose downloaded the full 1.5.9 zip file into the test folder. Unzipped it. There isn't a 1.5.9 folder only the overwritten Download folder. Is it how it supposed to work now or is it only my Windows?
