问题
Can windows store apps only access "library" files and not other locations on the hard drives of PCs? Like if I had a D drive that was full of video media that I wanted the app to have access to, is there no way to get to that? I've been searching for a while now and can't find anything but "knownfolder" examples and documentation.

In order to access files outside of the libraries and other specific locations, you'd need to use the FileOpenPicker or FolderPicker. You can find more information on File Access and Permissions for Windows Store apps at http://msdn.microsoft.com/en-us/library/windows/apps/Hh967755.aspx.
