Why is Hyper getting so big on my disk?

Windows 8 unfortunately caches everything you watch in the Hyper installation folder.
This cache is managed by Windows and cannot be cleared from within the app. To free up some space you can run the Windows 8 maintenance, however this usually automatically runs on a schedule, so you shouldn’t even have to worry about it at all.
By the way: this is not just a Hyper problem, but affects all Windows 8 Apps, which stream Music or video, or even just show images from the Internet.
