这是一个批处理 功能相对而言比较完善 主要实现了重命名txt文件（也可以对其略加修改以实现重命名多种文件）这个程序会提取出txt文件中的前几个字符加在原来文件名的后面如（1.txt 里面的类容123456 则重命名三个字符后会是1--123.txt）目的了不用多说主要是方便大概了解这个文本文件是什么类容的便于整理和区分 重命名后也可对其还原-This is a batch function is relatively complete re-named the main achievement of the txt file (can also be slightly modified in order to achieve their renaming multiple files) this program will extract the txt file in the first few characters added to the original the file name, such as (1.txt inside the class capacity of 123,456 re-named after the three characters will be 1- 123.txt) Needless to say the main purpose is to facilitate the understanding of this text file is probably what the class capacity of easy-to-order and the distinction could also be re-named for its reduction
