Windows 8 Explorer: Beautiful and practical blue up arrow

        In the previous Windows 8 late leak version, you can see that the address bar of Windows 8 Explorer has a small arrow on the left side, yellow, which is used to quickly access the upper folder, and there is a shortcut. The key is: Alt + up arrow.
This little arrow is obviously not available under the Win7 system, and in the new Windows 8 M3 later version, the yellow arrow turns blue, and it feels more integrated and more handsome with the default Aero theme.
Some friends said that the Win8 button is useless, you can quickly access each level of the folder by directly clicking on the folder block in the address bar, but if you encounter a folder with a particularly long name, You will find the benefits of this small up arrow.

this Win8 Explorer address bar to the left of the small blue arrow in Win7 system can also practice out of the first test to everyone, who knows how to get out of it?
Tip, you need a third-party software喔.
