操作系统实验。模拟文件系统实现的基本功能,了解文件系统的基本结构和文件的各种管理方法,加深理解文件系统的内部功能及内部实现。通过用高级语言编写和调试一个简单的文件系统，模拟文件管理的工作过程，从而对各种文件操作命令的实质内容和执行过程有比较深入的了解。-Experimental operating system. Simulation of the file system to achieve the basic functions, to understand the basic structure of the file system and documents a variety of management practices and deepen understanding of the file system s internal functions and internal realization. Through the use of advanced language writing and debugging a simple file system, simulating the work of document management process, which documents the substance of the operation command and the implementation of the process better.
