近来单位新开了个FTP服务器，各位管理员都知道的，文件多了就得定时删除啊，网上找了一圈，倒是有个几个软件可以用，但是总觉得效果不是很好，时灵时不灵的。只好痛下决心，自己做一个啦，小弟用的依旧是老掉牙的VC++6.0，不过软件能用就行啦。重点是思路。
主要功能：
1、 定时删除指定路径下的文件，支持修改时间或者创建时间来选择删除条件；
2、 自动保存已删除文件的名称、删除时间；
3、 支持拖拽或者浏览两种方式选取路径；
4、 可以保存路径信息，载入路径信息，省去软件退出之后又要加载之苦；
5、 意外退出，自动保存当前已有的路径信息；
6、 在重启软件的时候会自动载入路径信息。
直接上代码吧，有点乱，大家凑合着看哈
