1. Themain design ideas: put directory as N nodes of a binary tree using binary tree preorder completion of the plate directory search, positioning, from the root directory startedINT21H 4EH, the son of matching directory search function (CL = 10H), and to judge whether the outcome of the search for the directory, if yes, it may enter this directory, delete files after a search under subdirectory.
主要设计思想为:把目录当作N个结点的二叉树,采用二叉树的先序遍历完成对盘上目录的搜索、定位,即从根目录开始用INT21H的4EH号子功能搜索匹配目录(CL=10H)并判断搜索的结果是否为目录,若是则进入此目录,删除文件后继续搜索下一级子目录。
