一、课程设计目的 通过模拟文件系统的实现，深入理解操作系统中文件系统的理论知识。 二、课程设计要求 通过课程设计，要求学生主要掌握如下内容： 1．设计出文件系统中常用的数据结构； 2．理解文件系统的工作流程，给出程序流程图； 3．设计出文件系统中关键的算法； 4．模拟实现二级目录文件系统，并给出一组运行结果。 三、课程设计内容 根据实验指导书补充 四、文件系统实现-First, the curriculum designed by simulating the realization of the file system, in-depth understanding of the operating system file system of theoretical knowledge. Second, the curriculum design called for the adoption of curriculum design, the major requires students to master the following: 1. Design a file system commonly used in the data structure　2. Understanding file system work flow, process flow chart is given　3. Design a file system key algorithm　4. Simulation realize two file system directory, and gives a set of results. Third, the content of the curriculum design guidance based on the experimental four supplementary books, file system realize
