If all of the sites on your server need the exact same branding, layout, and functionality, then go ahead and make the change directly in the standard layout folder (after backing it up).
如果所有的站点都用同样的布局、界面及功能，那么请直接在_ layouts文件夹中做修改(最好在备份_ layouts文件夹后修改)。
Click Add path, navigate to your personal Sites directory, then click New Folder (the third button at the top right).
单击add path，找到您的个人站点目录，然后单击new Folder(右上角第三个按钮)。
