In Windows 8 there is no obvious way of checking how much space each Metro app is taking up–the option is actually hidden away in PC settings, read on to find out how to access it.
Viewing the Size of Metro Apps
Press the Windows + I keyboard combination and choose Change PC settings.
When the new Control Panel opens, head into the General section.
Scroll down on the right-hand side until you see the View app sizes button, then click on it.
This will bring up a dialog that will show you the size of each Metro app you have installed.
That’s all there is to it.
