  填DS-160表时如果隔20分钟没有变化，就会暂停。这时所有信息都删除了。这是为了保护你的个人隐私。 所以建议你每隔几分钟就要点一次“save”。这也只能暂时保存。需要将文件保存到本地盘时，要点击“Save Application to File”，然后再“save”。
  不过要记得存在什么地方，否则还是不能再次启用。 需要再次启用保存过的文件时，到“Getting Started”页，找“Import Application Date”来输入你的文件。 以下是英文解释： The DS-160 will “time out” approximately 20 minutes after the application has been idle。
   The “time out” is designed to protect your privacy。 If the application times out, all the data that has been entered will be lost。
   In order to guard against possible “time out” issues you should save the application at regular intervals while you are completing the application。
   To save the application, click the “Save” button at the bottom center of the application。 Clicking save will temporarily save your application。
   In order to permanently save your application, select the “Save Application to File” button。 Then, click the “Save” button on the File Download window。
   Identify a place on your computer to save the application file, browse to that location, and click the “Save” button on the Save As window。
   The system will download your application to the specified location。 Once the download is complete you can click “Close” to return to the application。
   You can then use the “Import Application Date” option on the “Getting Started” page to upload the data that you have already entered。
