今天在Linux服务器中解压一个zip的压缩包，提示如下错误信息：
[root@appsrv01 ZIP_BCSA_COURSES]# unzip BCSA_MEDIAS_BAK_20161118.zip error: Zip file too big (greater than 4294959102 bytes) Archive: BCSA_MEDIAS_BAK_20161118.zip warning [BCSA_MEDIAS_BAK_20161118.zip]: 31450041244 extra bytes at beginning or within zipfile (attempting to process anyway) error [BCSA_MEDIAS_BAK_20161118.zip]: start of central directory not found; zipfile corrupt. (please check that you have transferred or created the zipfile in the appropriate BINARY mode and that you have compiled UnZip properly) [root@appsrv01 ZIP_BCSA_COURSES]#
经过百度才知道，原来unzip不能解压超过4GB的zip文件（没想到这么弱。。。），需要把鸟枪换炮（p7zip）了。
