>I have a folder with many Excel files. What would be the most elegant way to get the filename of the newest file? I know I can cycle through all the files and do a compare on the dates, but since I am going to be running this on a web server I am afraid that will incur too much overhead.

Wish it were 2.0:) You can use Array.Sort with an IComparer. ie:

 DirectoryInfo di = new DirectoryInfo(stringPath);
 FileInfo[] fi = di.GetFiles("*.xls");
 MyComparer mc = new MyComparer();
 Array.Sort(fi, mc);
 // fi[0] is last written after sort

public class MyComparer:IComparer
{
   public int Compare(object x, object y)
   {
     return ((FileInfo)y).LastWriteTime.CompareTo( ((FileInfo)x).LastWriteTime );
   }
}
