160行代码实现文件检查器(GUI)

工作中，每个月都会对数据进行汇总，想要方便一些，就写了一个文件校验器。
不同于市面上常见的批量重命名，这个具有自动校验功能，可以检验文件名的连续性，会提示缺失的文件，同时，还会校验文件数量，MD5值，路径等。
功能
1.快速批量校验MD5值校验。
2.文件大小、文件路径显示
3.文件日期连续性校验，对缺失日期文件进行提示。(不完善)
4.搜索框支持中文搜索
5.对小于<10KB的文件会提示异常文件。方便快速定位异常文件
以下是界面截图&源代码&打包文件

打包好的EXE(不放心的，可以审查源码。打包只是方便使用)

1.文件过多时候，没有滚动条，不是很方便查看
2.界面好像就显示330条就不显示了，也不提示完成。。。
运行了下源码，报错了
