当我尝试执行它时.

基本上，我将其设置为一次仅尝试复制一个***文件夹，并且对于每个***文件夹，它都使用我之前拥有的递归函数.它应该为第一级文件夹和根文件夹中的任何文件保存延续令牌，以便它可以在下一次执行中从它停止的地方继续.这样一来，我的递归函数堆栈中就不会涉及到令牌.

Basically, I set it up to only try to copy one top-level folder at a time, and for each one of those it uses the recursive functions I had before. It should save continuation tokens for that first level of folders and any files in the root folder so it can pick up in the next execution where it left off. This way, the tokens are not involved in my recursive stack of functions.

function copyDrive() {


  var originFolder = DriveApp.getFolderById(originFolderID);
  var destination = DriveApp.getFolderById(destinationID);

  var scriptProperties = PropertiesService.getScriptProperties();
  var fileContinuationToken = scriptProperties.getProperty('FILE_CONTINUATION_TOKEN');
  var fileIterator = fileContinuationToken == null ?
    originFolder.getFiles() : DriveApp.continueFileIterator(fileContinuationToken);
  var folderContinuationToken = scriptProperties.getProperty('FOLDER_CONTINUATION_TOKEN');
  var folderIterator = folderContinuationToken == null ?
    originFolder.getFolders() : DriveApp.continueFolderIterator(folderContinuationToken);

  try {
    var rootFileName;
    while(fileIterator.hasNext()) {
      var rootFile = fileIterator.next();
      rootFileName = rootFile.getName();
      rootFile.makeCopy(rootFileName, destination);
      }

    var folder = folderIterator.next();
    var folderName = folder.getName();
    var folderCopy = folder.makeCopy(folderName, destination);


    copyFiles(folder, folderCopy);

  } catch(err) {
    Logger.log(err);
  }

  if(fileIterator.hasNext()) {
    scriptProperties.setProperty('FILE_CONTINUATION_TOKEN', fileIterator.getContinuationToken());
  } else {
    scriptProperties.deleteProperty('FILE_CONTINUATION_TOKEN');
  }
  if(folderIterator.hasNext()) {
    scriptProperties.setProperty('FOLDER_CONTINUATION_TOKEN', folderIterator.getContinuationToken());
  } else {
    scriptProperties.deleteProperty('FOLDER_CONTINUATION_TOKEN');
  }

};

  var fileContents = passedFolder.getFiles();
  var file;
  var fileName;

  while(fileContents.hasNext()) {
