    <p>I have a WP7 application that I run successfully on both WP7 and WP8 devices. In the app I download audio files using the <code>BackgroundFileTransfer</code> service and store the files to the <code>shared/transfers</code> folder. I then create <code>AudioTrack</code>s by giving a URI to the downloaded file locations.</p> <pre class="lang-cs prettyprint-override"><code> Uri episodeLocation; try { using (IsolatedStorageFile iso = IsolatedStorageFile.GetUserStoreForApplication()) { Debug.WriteLine(" *** Creating track, file exists: " + iso.FileExists("shared/transfers/song.mp3")); } episodeLocation = new Uri("shared/transfers/song.mp3", UriKind.Relative); } catch(Exception) { return null; } return new AudioTrack(episodeLocation, "Track name", "Album name", "", new Uri("/path/to/logo", UriKind.Relative)); </code></pre> <p><strong>This works great on both Windows Phone 7 and Windows Phone 8 devices</strong> - audio player is able to play the track just fine. The debug output prints <code>True</code> as the result for the test if file exists. </p> <p>I've now converted the application in Visual Studio 2012 to be a Windows Phone 8 application. If I now run the application in Windows Phone 8, I get a <code>System.IO.FileNotFoundException</code> external exception from the player. Also in the converted version the debug output prints <code>True</code> when checking if the file exists. </p> <p><strong>I only converted the app from a WP7 to WP8 app</strong> and I cannot refer to files in <code>shared/transfers</code> any more.</p> <p>Why?</p> <p>What's the proper way to do this? </p> <p>I already tried referring to the files by using the URI <code>isostore:/shared/transfers/song.mp3</code> but that didn't seem to have an effect. </p>

    1. COIn fact, it seems moving the audio files to any other directory or even the root directory yields the same result: FileExists() returns true, but Audio player throws FileNotFound exception.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
