摘要
磁盘压缩技术是一种减少磁盘上数据存储开销的技术总称．使用磁盘压缩技术，可以在相同容量的磁盘上存储更多的数据．磁盘压缩软件并没有真正提高磁盘的物理容量，它只是减少了数据的容量．当用户将数据存储在磁盘上时，磁盘压缩软件在不丢失数据的前题下，对数据进行压缩，当用户访问磁盘数据时，压缩软件将压缩数据恢复到原来的状态．由于压缩软件常驻内存，它自动的与ＤＯＳ配合，使计算机的所有操作和过去一样．
The disk compressing technique is to reduce the disk data’s keeping expense . Using the disk compressing technique can keep more data in more date in the same disk.The disk compressing software doesn’t truly increase the disk’s physical size,it only decreases the data’s keeping expense.When the user keeps the data in the disk ,the disk compressing software compresses the data and whole file .When the user wants the disk data ,the software recovers the compressed data to the oriqinal state.After the user installs the disk compressing software ,it works with the DOS automatically ,so all the computer operations are the same as before.
