var file = await ApplicationData.Current.LocalFolder.GetFileAsync(
8.1 got something like this, I tried it worked.
var folder = ApplicationData.Current.LocalFolder;
var file = await folder.TryGetItemAsync("mytext.txt") as IStorageFile;
if (file == null)
{
//do what you want
}
else
{
//do what you want
}
