The browser downloads the document to a temporary folder, then tells your system to run %PRODUCTNAME and open the document in %PRODUCTNAME. This is the default when you did not enable the Browser Plug-in and chose to open the document with %PRODUCTNAME when you were first asked.
浏览器将文档下载到临时文件夹，然后告知系统运行 %PRODUCTNAME，并在 %PRODUCTNAME 中打开该文档。如果在首次提示时您没有启用浏览器插件，且选择用 %PRODUCTNAME 打开文档，则这会是默认设置。
