I found a solve:

function myExportToGoogleDrive1() {
  var threads = GmailApp.search("label:TestExportEML");  
  GmailApp.markThreadsRead(threads);
  Logger.log(threads)
  var messagesArray = []     
  
  var newFolder = DriveApp.createFolder("dddddddddddddddddddddd").getId();

  for (var i=0; i< threads.length; i++) {
    var messages = threads[i].getMessages();

      for (var j=0; j< messages.length; j++) {

        var myID = messages[j].getId();
        var msg = GmailApp.getMessageById(myID);
        var msgRaw = msg.getRawContent();

        var msgBlob = Utilities.newBlob(msgRaw, 'message/rfc822', 'example.eml');
        
        var ssss = DriveApp.getFolderById(newFolder).createFile(msgBlob);
        var filename = GmailApp.getMessageById(myID).getSubject();
        
        ssss.setName(filename);
      }
  }
}

Thanks for your help.
