批量文件名加前缀

前言

今天开始看新的资料了, 文件夹里一坨文件, 不到500个.
因为不是一天的事情, 很有可能以后再继续学习时, 找不到下一个该学习哪个.
据我自己的经验, 先要给这些文件, 加一个数字前缀. 看完一个, 就记录我看完这个了. 等下回, 我就找下一个序号来学习.
我就习惯性的开始给文件改名, 改了几十个,突然意识到,不能手工这么玩…
去codeproject上找文件改名的工程, 很多, 很先进(支持正则表达式).
但是我不需要那么先进的功能, 只需要给文件改名, 加一个数字前缀而以.
用到的API不多 : FindFirstFile, MoveFile, FindNextFile, FindClose.
就自己写了一个, 吃完晚饭, 边写边调试, 一个小时完成.
写的工具支持拖拽(文件或文件夹), 只给文件加前缀序号, 文件夹不动, 一键搞定.
自己写几句代码做重复的事情, 还是有点幸福的感觉:)
