请问如何在windows平台下处理这个文件？

D盘:\chengxu\目录下有n个目录（目录举例为：1942-干休四所,1943-电器），
“1942-干休四所”目录下有个文件“1942-干休四所”，内容如下：
interface Vlan-interface1083
description baijinhan-1-adsl
ip address 172.16.1.2 255.255.255.240
#
interface Vlan-interface1800
description zhuanxian2
ip address 192.168.1.1 255.255.255.248
#
interface Vlan-interface1802
description zhuanxian3
ip address 192.168.10.1 255.255.255.240
ip address 192.168.20.1 255.255.255.224 sub
#
interface Vlan-interface1803
description zhuanxian4
shutdown
ip address 192.168.32.1 255.255.255.248
#

“1943-电器”目录下有个文件“1943-电器”，内容如下：
interface Vlan-interface2098
description abc-bar
ip address 172.30.1.2 255.255.255.240
#
interface Vlan-interface1800
description zzz
ip address 192.168.100.1 255.255.255.248

最终需要在目录D盘：\chengxu\result下，生成一个最终文件，内容为：
interface Eth-Trunk1.100

请注意：红色部分是取自原有目录下的相应字段，且Eth-Trunk1.xxx是递增的，
若目录下的子目录有n个，如何适应扩展呢？比如有这些目录:1942-a,1943-b,1944-c,1945-d,1946-a....
