Learn how to use the file picker in Open files and folders with a picker. By default, your app can only access files and folders in the user's Downloads folder that your app created.
However, you can gain access to files and folders in the user's Downloads folder by calling a file picker FileOpenPicker or FolderPicker so that users can navigate and pick files or folders for your app to access.
CreateFileAsync is overloaded so that you can specify what the system should do if there is already an existing file in the Downloads folder that has the same name. When these methods complete, they return a StorageFile that represents the file that was created. This file is called newFile in the example. CreateFolderAsync is overloaded so that you can specify what the system should do if there is already an existing subfolder in the Downloads folder that has the same name.
When these methods complete, they return a StorageFolder that represents the subfolder that was created. This file is called newFolder in the example. In addition to the default locations, an app can access additional files and folders by declaring capabilities in the app manifest or by calling a file picker to let the user pick files and folders for the app to access.
Apps that declare the AppExecutionAlias extension have file-system permissions from the directory that they are launched from in the console window, and downwards. When your app retrieves a file or folder via a picker, a file activation, a drag-and-drop operation, etc. If you would like to automatically access the file or folder in the future, you can add it to the FutureAccessList so that your app can readily access that item in the future.
You can also use the MostRecentlyUsedList to easily manage a list of recently-used files. The following table lists additional locations that you can access by declaring one or more capabilities and using the associated Windows. Storage API. This example adds the restricted broadFileSystemAccess capability. In addition to specifying the capability, the rescap namespace must be added, and is also added to IgnorableNamespaces. For a complete list of app capabilities, see App capability declarations.

Hi there, Microsoft Word has suddenly started asking for "Grant file access" when I try to open documents. I select the document and hit "OK", but it says, "Word cannot open the document: user does not have access privileges" I have not made any recent updates. I can't open any of my documents! I have a different issue. All of my hyperlinks in my word document are making me personally grant access to even my own document hyperlinks to files.
