Directory Files

this might do it: // Only get files that begin with the letter "c." string[] dirs = Directory.GetFiles(@"c:\", "c*"); Console.WriteLine("The number of files starting with c is {0}.", dirs.Length); foreach (string dir in dirs) { Console.WriteLine(dir); } and also: DirectoryInfo di = new DirectoryInfo(@"c:\"); // Get only subdirectories that contain the letter "p." DirectoryInfo[] dirs = di.GetDirectories("*p*"); Console.WriteLine("Number of directories with a p: {0}", dirs.Length); // Count all the files in each subdirectory that contain the letter "e." foreach (DirectoryInfo diNext in dirs) { Console.WriteLine("The number of files in {0} with an e is {1}", diNext, diNext.GetFiles("*e*").Length); } Happy coding

u can use fileInfo class of IO Package to get the names of all the files in particullar directory. then add these name tu combobox manually by loop....
