操作系统文件管理实验：利用交互式命令实现树型目录结构和文件管理,同时利用位示图表示外存的分配情况，新建文件时分配必要的空间，模拟文件分配表记录文件在外存上的存储方式。了解系统对文件的操作。 在文件中保存目录内容，创建文件或子目录可以用命令行命令：MD、CD、RD、MK（创建文件）、DEL（删除文件）和DIR(Operating system file management experiment: the use of interactive command tree directory structure and file management, while taking advantage of the bit map indicates the distribution of the external memory, and allocate the necessary space when a new file is created, the simulation file allocation table log file is stored in the external memory way. Understanding of the system operation on the file. Save the contents of a directory in the file, create a file or subdirectory can use the command-line command: MD, CD, RD, MK (create a file), DEL (delete files) and DIR)
