Libraries and Other Special Folders
With the right capability granted to your app, you can access the user’s Music, Pictures, or Videos libraries without any prompt or file picker. (The Documents Library capability is more restrictive, because it works only for file type associations registered by the app, discussed in Chapter 21.) The same is true for a few more special folders: the HomeGroup folder, the removable devices folder, and the DLNA devices folder.
Accessing Known Folders
Accessing any of the special folders is trivial, thanks to a static KnownFolders class that exposes several StorageFolder properties. As with the different types of app files, all you need to do is start off with the right StorageFolder. For example:
