    <p>What about creating your own directory traversal function and using the <a href="http://msdn.microsoft.com/en-us/library/9k7k7cf0.aspx" rel="nofollow noreferrer">C# <code>yield</code> operator</a>?</p> <p>EDIT: I've made a simple test, I don't know if it's exactly what you need.</p> <pre><code>class Program { static string PATH = "F:\\users\\llopez\\media\\photos"; static Func&lt;string, bool&gt; WHERE = s =&gt; s.EndsWith(".CR2") || s.EndsWith(".html"); static void Main(string[] args) { using (new Profiler()) { var accepted = Directory.GetFiles(PATH, "*.*", SearchOption.AllDirectories) .Where(WHERE); foreach (string f in accepted) { } } using (new Profiler()) { var files = traverse(PATH, WHERE); foreach (string f in files) { } } Console.ReadLine(); } static IEnumerable&lt;string&gt; traverse(string path, Func&lt;string, bool&gt; filter) { foreach (string f in Directory.GetFiles(path).Where(filter)) { yield return f; } foreach (string d in Directory.GetDirectories(path)) { foreach (string f in traverse(d, filter)) { yield return f; } } } } class Profiler : IDisposable { private Stopwatch stopwatch; public Profiler() { this.stopwatch = new Stopwatch(); this.stopwatch.Start(); } public void Dispose() { stopwatch.Stop(); Console.WriteLine("Runing time: {0}ms", this.stopwatch.ElapsedMilliseconds); Console.WriteLine("GC.GetTotalMemory(false): {0}", GC.GetTotalMemory(false)); } } </code></pre> <p>I know that you cannot rely to much on <a href="http://msdn.microsoft.com/en-us/library/system.gc.gettotalmemory(VS.71).aspx" rel="nofollow noreferrer"><code>GC.GetTotalMemory</code></a> for memory profiling, but in all my test runs display a little less memory consumption around(100K).</p> <pre>Runing time: 605ms GC.GetTotalMemory(false): 3444684 Runing time: 577ms GC.GetTotalMemory(false): 3293368</pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
