【GAS】Googleドライブに親フォルダと子フォルダを作成するサンプル

function CreateParentFolderChildFolderlSample() {
  const parentFolderName = "parent"
  const ChildFolderName = "Child"

  //親フォルダ
  let parentFolder = DriveApp.createFolder(parentFolderName)
  console.log(parentFolder.getName());
  console.log(parentFolder.getId());
  //あえて、親フォルダのIDからフォルダを取得
  let parentFolder2 = DriveApp.getFolderById(parentFolder.getId());
  console.log(parentFolder2.getName());
  console.log(parentFolder.getId());

  //親フォルダの中に子フォルダを作成
  let ChildFolder = parentFolder2.createFolder(ChildFolderName);
  console.log(ChildFolder.getName());
  console.log(ChildFolder.getId());

}
