用Winrar来解压

dos下：
rar x test.rar

如果要解开，当然使用RAR或WinRAR啦，如果要编程解开，可以调用WINRAR的动态连接库：
下面是封装的一个类，拿去用用吧：

Windows下使用WinRAR(有汉化版),操作与WinZip类似.
DOS下用RAR解压,可用图形界面,也可用rar x <Archive> <Path>
或用RAR里的UNRAR解压.

[SkyNet]

同意FireAngel观点

[vbdabster]

用winrar就可以了，呵呵

[jimgreen]

用这些东西干吗，用个windows commander 不就全解决了吗？

[panch]

用WINRAR吧。

[starwalker]

WINZIP也可以的

[SCORPIONS]

下载一个winrar
