本实验的目的是使学生在学习文件系统原理的基础上，通过参考成熟的操作系统中文件系统的设计，实现一个简单的多用户文件系统，加深对文件系统的功能、内部结构包括逻辑结构以及物理结构的理解。有兴趣的同学可以在此基础上进行功能的扩展以及性能的优化。-The purpose of this experiment is to enable students to learn the file system on the basis of principle, by reference to the sophisticated design of the operating system, file system, implement a simple multi-user file system, the file system to enhance the function of the logical structure and the internal structure includes understand the physical structure. Interested students can be expanded and optimize the performance of the functions on this basis.
