软件名称：批量更名专家 1.5
整理日期：2002.11.11
最新版本：1.5 Build 1111
文件大小：888KB
软件授权：共享软件
使用平台：Win9x/Me/NT/2000
发布公司：Home Page
软件简介：
　　是一款优秀的批量文件改名工具，更名速度极快。简明的资源管理器界面，上手极为方便。
提供更名前预览功能，提供批量修改文件属性和日期，修改扩展名，修改大小写，可以插入，
删除，替换，独特的序数改名功能，直接编辑文件名，根据MP3文件的Id3信息改名等。
主要工具：TRW2000 W32DASM UPX
用UPX脱壳，注册时需输入8位以上注册名，重启验证。
启动程序输入"nightstar/987654321",退出用W32DASM加载，查找"RWCode"，代码如下

最后连接1150218012111212114

总结：
设name的长度为x,第几位为y，第y位的ASCII值为Ny，第(x-y)位的ASCII值为N(x-y)
1.N2,N4,N6,N8,...= Ny*N(x-y) and $3
2.n3,n9...3的倍数 = Ny+N(x-y)
3.N1,N5,N7..= Ny+$5
将上面的值转化为10进制值,按N1,N2,N3..Nx的顺序连起来。

不好意思，写的比较乱。
