摘要： 在大规模分布式多计算机系统中，内外存之间容量的差距正在减小，这极大地影响了操作系统中存储管理的设计和实现。操作系统设计者必须解决在外存容量不足的情况下如何实施存储扩充。提出了指令对文件直接寻址的概念及其实现方法，并分析了指今对文件直接寻址如何解决了这个问题。

Abstract: in a large-scale distributed multi-computer system. the capacity gap between main memories and external storage devices is decreasing. This greatly affects how memory management is designed and implemented in operahng system. What operating system designers must solve is how to implement memory expansion when there is not enough external storage. In this paper, the author puts forwards the concept and implementation of instruction Directly Access File and discusses how the problem is solved.
