Google 三个 Office Apps (Docs, Sheets, Slides) 在最新版本加入了垃圾桶，可减少档案被意外删掉的情况。
Simply select Trash from the navigation menu in your Docs, Sheets, or Slides app, and you’ll be given the option to restore or permanently delete any files that you’ve trashed.
在 App 内，删除的档案都会被移至垃圾桶内，只要在左边 Menu 按 “垃圾桶” 内里就会列出被删除的档案，用家可以选择将档案还原，又或将档案永久删除。
