简单的二级文件系统

在任一OS下，建立一个大文件，把它假象成硬盘，在其中实现一个简单的模拟文件系统。 编写一管理程序对此空间进行管理，要求：



1． 实现盘块管理



2． 实现文件的读写操作



3． 每组最多2人，小组内要有明确分工，课程设计报告中设计部分可以相同，个人实现部分不同



参考建议：



将模拟硬盘的文件空间划分为目录区，文件区；采用位示图进行空间管理，盘块的分配使用显示链接（FAT表）的方式。-Simple two file system in either OS, the establishment of a large file, the illusion of it into the hard drive, in which a simple simulation file system. The preparation of a management program space management requirements: 1. Disk block management 2. File read and write operations. Each set of up to 2, the group must be a clear division of labor, the design part of the curriculum design report can be the same individuals to achieve some of the different reference proposal: to the analog hard drive file space is divided into a directory area, file area　bit diagram space management disk blocks allocated using the link (FAT table).
