Winform文件夹内容同步更新、备份、日志、恢复

相信大家做项目或者处理文件时候经常要用到备份的功能，这里给大家做一个可以同步更新文件夹内容并且备份的Winform程序，目前地址路径在App.Config文件里面设置，如需更改直接用记事本编辑即可，下面放代码和截图。

1.CS代码：

        string Timing = ConfigurationManager.AppSettings["Timing"].ToString();
        string backPath = ConfigurationManager.AppSettings["backUpPath"].ToString();
        int count = 0;

        string fullPath = "D:/backup/backup.txt";//设置日志地址
