Samsung Developers recently released a tutorial video which talks about the Content API example web application. This is one of many example applications which are available for download directly within the Tizen Eclipse IDE.
The Content API allows developers to discover multimedia content stored on device and to query that content. The example application provides a simple "browser" view showing the content on your device.
See Content API Guide from the Tips and Tech section for more detailed information on this API. The original video is shown below, along with an "add-on" which shows me demonstrating the same application on my machine, including use of the Tizen Emulator and IDE.
