合并文件夹二

背景

需要按照一定规则合并大量文件夹
这些文件夹是按照命名分类的
这些文件夹的命名存在一定规律，比如A_001_005,A_004-010，需要把连续的文件夹合并

需求说明

1、根据指定目录下，找到文件夹所在根目录；该目录下包含需要合并的文件夹
如：

2、将待合并的文件夹，合并到一个主文件夹中；
该合并规则如下：

规则一：

将该三个文件夹合并为一个文件夹：

规则二：

将该两个文件夹合并为一个文件夹：

【注】规则一与二的区别便是：规则一是从001开始，规则二是从004开始。也就是开头并不能确定是从第几景开始的，可能是001或者002或者003……

规则三：

从文件夹名字可以看出：中间缺少了006景数据，那么要合并的文件夹就是

最终结果表示为：

3、将每个文件夹中的
四个文件：copyfinished、created、对应的paf文件进行剪切到合并后文件夹中。
4、全部合并完成后，删除原文件夹
