python工具, 转储WIN10锁屏壁纸
1. 关于WINDOWS10 锁屏壁纸C:\Users\MIS\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets备注一下：MIS：是你要的用户名文件夹Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy：这个文件夹是随机的。但是前面Microsoft.Windows.ContentDeliveryManager这一段是不会变的。其他的文件夹都是一样的。

2. 每个文件的MD5码储存在目标目录的 sqllite.db数据库文件中
3. 转储时, 对文件基于md5码判断是否为新文件, 如果是新文件就复制过来, 按现有的数字文件名, 存为 最大数字+1.jpg
4. 需手工随缘运行,未设置定时. 大概就是你哪天觉得今天的锁屏壁纸真漂亮的时候.
