Google脚本，根据上次修改日期删除文件夹中的文件

function deleteFilesByModifiedDate(folderId, daysAgo) {
  var folder = DriveApp.getFolderById(folderId);
  var files = folder.getFiles();
  var currentDate = new Date();
  var daysAgoDate = new Date(currentDate.getTime() - daysAgo * 24 * 60 * 60 * 1000);

  while (files.hasNext()) {
    var file = files.next();
    var modifiedDate = file.getLastUpdated();

    if (modifiedDate < daysAgoDate) {
      file.setTrashed(true);
    }
  }
}
