The WinRT compression API only works for a single data stream and not for multiple files or a folder. For that you need to write a WinRT component to use the .NET System.UI.Compression API, or you can use third-party libraries. See this thread: http://social.msdn.microsoft.com/Forums/en-US/winappswithhtml5/thread/9f486365-56e8-4c46-9e26-78c565d0109a

Also see this blog post that mentions using the .NET APIs for this purpose:

We will publish an unzip WinRT component the coming weeks for x86/x64/ARM

See the current APIs spec in CoffeeScript here: https://gist.github.com/3934325

Maybe we will be tailoring the API to the whole IStorageFile/Folder schema and add zipping of files in the future.

Glad to hear it, Phil!

Answer 6

Did you ever get this into github? I've been trying to find it, with no luck.

Answer 7

Actually yes, opened the ZIP-WinRT Component repository on Friday. Please see the accompanied specs on how to use the component.
