title: Where are the files created with CreateFileAsync?
body: <p>When I call the following function, it should create a .txt file and write a sentence in it. It seems to execute without any errors. But I cannot find where this file is stored/located after being created. I ran a Windows Search to look for the file but nothing came up. Where is this file located? Also, what is the best folder/location to put a .txt file that the program uses? Should I put it in Solution Explorer of Visual Studio or Debug folder?</p>
  
  <pre><code>    private async void CreateFile() {
       try {
        // Create sample file, replace if exists.
        StorageFolder storageFolder = ApplicationData.Current.LocalFolder;
        StorageFile sampleFile = await storageFolder.CreateFileAsync("sample.txt", CreationCollisionOption.ReplaceExisting);
  
        sampleFile = await storageFolder.GetFileAsync("sample.txt");
  
        await FileIO.WriteTextAsync(sampleFile, "Swift as a shadow!");
       } catch (Exception ex) {
        textBox.Text = ex.ToString();
       }
      }
  </code></pre>
