随着计算机应用技术的发展,计算机存储、处理的信息量越来越大,一些大的系统软件(如WIN 95/98)、应用软件及游戏等都要占用大量的存储空间,因此,现在许多用户的微机上都配上了大容量的磁盘,而如何充分利用这些大硬盘也就成为用户十分关心的话题.下面就从文件在磁盘上的存储方式谈起,说说文件分配表对磁盘利用率的影响.文件的存储方法及FAT为了将文件存储到磁盘上,必须采取某种方法来进行磁盘空间的分配,即在磁盘的什么位置上以什么样的方式存储文件.一种比较直接的方法是在磁盘上连续地存储文件,这样只要知道了文件的起始位置就能够访问该文件的全部内容了.这种方法简单方便,但同时也会产生许多问题,其中最主要的就是所谓“磁盘碎片”问题.假设在磁盘上已存放好了两个文件,它们的位置是连续的,此时,删除第一个文件,再建立一个新文件,如果这个新
With the development of computer application technology, the amount of information stored and processed by computer has been increasing. Some large system software (such as WIN 95/98), application software and games occupy a large amount of storage space. Therefore, many The user’s computer is equipped with a large capacity disk, and how to make full use of these large hard drive has become a user is very concerned about the topic.From the file on the disk storage method talk about file allocation table for disk utilization The impact of the rate.File storage methods and FAT In order to store the file to disk, you must take some method to allocate disk space, that is, in what position on the disk in what way to store the file. A more direct The method is to continuously store the file on the disk, so that as long as you know the starting position of the file can access the entire contents of the file.This method is simple and convenient, but also has many problems, of which the most important is the so-called “ Disk Fragmentation. ”Assuming that two files have been stored on the disk, their location is continuous, this time, delete the first file, and then create a new file If this new
