Windows.Storage.Pickers.PickerLocationId.Desktop;
folderPicker.FileTypeFilter.Add("*");
Windows.Storage.StorageFolder
folder = await folderPicker.PickSingleFolderAsync();
if (folder != null)
{
// Application now has read/write access
to all contents in the picked folder
// (including other sub-folder contents)
Windows.Storage.AccessCache.StorageApplicationPermissions.
FutureAccessList.AddOrReplace("PickedFolderToken", folder);
txtBlock.Text = "Picked folder: " + folder.Name;
