Examples

This example demonstrates how to add an item to the app's FutureAccessList and MostRecentlyUsedList.

StorageFile file = await savePicker.PickSaveFileAsync();
if (file != null)
{
    // Add to MRU with metadata (For example, a string that represents the date)
    string mruToken = Windows.Storage.AccessCache.StorageApplicationPermissions.MostRecentlyUsedList.Add(file, "20120716");

    // Add to FA without metadata
    string faToken = Windows.Storage.AccessCache.StorageApplicationPermissions.FutureAccessList.Add(file);  
}
else
{
    // The file picker was dismissed with no file selected to save
}

savePicker.pickSaveFileAsync().then(function (file) {
    if (file) {
        // Add to MRU with metadata (For example, a string that represents the date)
        var mruToken = StorageApplicationPermissions.mostRecentlyUsedList.add(file, "20120716");

        // Add to FA without metadata
        var faToken = Windows.Storage.AccessCache.StorageApplicationPermissions.futureAccessList.add(file);
    } else {
        // The file picker was dismissed with no file selected to save
    }
});

It is recommended that you store the tokens returned by StorageApplicationPermissions.MostRecentlyUsedList.Add and StorageApplicationPermissions.FutureAccessList.Add so that you can use them to retrieve the respective list entry for the item that you added. In the example, we store the tokens in mruToken and faToken respectively but we don't do anything else with them.

Additionally, the savePicker variable in the example contains a FileSavePicker object that was created by the sample. To learn more about saving files with file picker, see How to save files through . To learn about accessing files, see Quickstart: Accessing files with .
