Tak tady je ten program:

Musíš ho ale spustit jako správce, protože výsledný dokument bude chtít zapsat do: C:\document.csv

                folderBrowserDialog1.Description = "Open a folder which contains files";
                folderBrowserDialog1.ShowNewFolderButton = false;
                folderBrowserDialog1.RootFolder = Environment.SpecialFolder.MyComputer;
                if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
                {
                    string folder = folderBrowserDialog1.SelectedPath;
                    DirectoryInfo d = new DirectoryInfo(folder);

                    using (System.IO.StreamWriter fileResult = new System.IO.StreamWriter(@"C:\document.csv"))
                    {

                        foreach (var file in d.GetFiles("*.*"))
                        {
                            string line = "";
                            System.IO.StreamReader file2 = new System.IO.StreamReader(file.FullName);
                            while (( line = file2.ReadLine()) != null)
                            {
                                line = line.Replace("(","");
                                line = line.Replace(")","");
                                List<string> items = line.Split(' ').ToList();
                                if (items.Count > 2)
                                fileResult.WriteLine(items[0] + ";" + items[1] + ";" + items[2]);
                            }

                        }

                    }

                }
