See Also: IsolatedStorageFile Members
This object corresponds to a specific isolated storage scope, where files represented by System.IO.IsolatedStorage.IsolatedStorageFileStream objects exist. Applications can use isolated storage to save data in their own isolated portion of the file system, without having to specify a particular path within the file system. Since isolated stores are scoped to particular assemblies, most other managed code will not be able to access your code's data (highly trusted managed code and administration tools can access stores from other assemblies). Unmanaged code can access any isolated stores.
For more information, see Isolated Storage.
Isolated storage is not available for win8_appname_long apps. Instead, use the application data classes in the Windows.Storage namespaces included in the wrt API to store local data and files. For more information, see tp://go.microsoft.com/fwlink/?LinkId=229175 in the Windows Dev Center.
