第一次调用 获取D*f目录 () 后，写入C盘配置文件，以后再打开软件就不再寻找注册表以节省资源，如果注册表信息找不到或者错误的注册表，程序会自动提示手动指定D*f目录的。希望能给朋友们带来方便和帮助，不喜勿喷。(The first call to get D*f directory (), written C configuration file, then open the software is no longer looking for the registry to save resources, if the registry information is missing or incorrect registry, the program will be automatically prompted to manually specify the D*f directory. Hope to bring convenience and help to friends, do not want to do it.)
