磁盘文件管理系统：

能浏览、删除、复制文件

我用三个子程序open,copy,delete分别实现了对磁盘文件的浏览，复制和删除。主要都是调用3DH，3FH，3EH，40H，41H等功能，没有什么特别的。主要困难在于路径的输入和存取。其他琐屑的细节问题只是比较耗时间-Disk document management system: able to browse, delete, copy paper I use three subroutines open, copy, delete, respectively, to achieve a disk file browser, copy and delete.

Other trivial details of the problem is comparing the amount of time spent
