✅ I cant combine folder paths

string ilce = duzenleIlce.Text;
string mahalle = duzenleMah.Text;
string ada = duzenleAda.Text;
string parsel = duzenleParsel.Text;
string islem = duzenleIslemCombo.Text;
string klasorAdi = string.IsNullOrEmpty(ada) ? parsel : ada + "_" + parsel;
string baseFolderPath = Settings1.Default.settingsFolderPath + "\\LIHKAB_3100-800\\";

string folderPath = Path.Combine(baseFolderPath, ilce, mahalle, klasorAdi);
