News文件夹调用了Kindeditor ,请问如何配置上传路径

file_manager_json.ashx //根目录路径，相对路径
String rootPath = "../attached/";
//根目录URL，可以指定绝对路径，比如 http://www.yoursite.com/attached/
String rootUrl = aspxUrl + "../attached/";------------------------------------------------------------------------
upload_json.ashx //文件保存目录路径
private String savePath = "../attached/";
//文件保存目录URL
private String saveUrl = "../attached/";
要怎么写啊！
