Don't know exactly what your intentions are with a Listview.
But beside the fact that Directories has a GetFiles method it also has

string[] folders = Directory.GetDirectories(folderBrowserDialog1.SelectedPath);

ddanbe, but this will only get folders, not files. I think he want to get all files in wanted directory, and in all subdirectories, if Im not mistaken.
This for example will return all the file paths:
string[] filePaths = Directory.GetFiles(@"C:\1", "*.*", SearchOption.AllDirectories);

@Mitja, you are right, but line 31 of his code already gives the OP the files in that directory.
Don't know what the intentions really are, but your suggestion of

string[] filePaths = Directory.GetFiles(folderBrowserDialog1.SelectedPath, "*.*", SearchOption.AllDirectories);

is very good!

And here is an example of how to get all files (only names if you want) from a directory + files in all sub directory (change the file path):

class Program
    {
        static void Main(string[] args)
        {
            List<string> allFiles = GettingFiles(@"C:\1");
        }

        public static List<string> GettingFiles(string path)
        {
            List<string> listFiles = new List<string>();

            //1. get files from the current directory:
            string[] currentFiles = Directory.GetFiles(path, "*.*");
            foreach (string file in currentFiles)
                listFiles.Add(file);

            //2. get files from other sub directories:
            string[] directories = Directory.GetDirectories(path);
            foreach (string dir in directories)
            {
                string[] files = GetFilesFromDirectory(dir);
                listFiles.AddRange(files);
            }

            //for the end, lets get only the names of the files (remove the path):
            for (int i = 0; i < listFiles.Count; i++)
            {
                string fileName = Path.GetFileName(listFiles[i]);
                listFiles[i] = fileName;
            }
            return listFiles;
        }

        private static string[] GetFilesFromDirectory(string path)
        {
            string[] files = Directory.GetFiles(path);
            return files;
        }
    }

btw, thx ddanbe :)
Hope it helps,
Mitja
