我有三个文件1.zip，1.z01 1.z02。我想通过右键单击1.zip并选择“在此处提取”来将它们提取并加入文件中。但是然后出现一个错误：
7-Zip 9.04 beta版权所有（c）1999-2009 Igor Pavlov 2009-05-30 p7zip版本9.04（locale = en_US.utf8，Utf16 = on，HugeFiles = on，2个CPU）
错误：/home/tim/Desktop/1.zip：无法打开文件作为存档
错误：1
我想知道这是什么问题以及如何解决？
谢谢并恭祝安康！
添加： 我对“ unzip -FF”的使用是否错误？似乎不起作用：
$ unzip -FF 1.zip
Archive: 1.zip
warning [1.zip]: zipfile claims to be last disk of a multi-part archive;
attempting to process anyway, assuming all parts have been concatenated
together in order. Expect "errors" and warnings...true multi-part support
doesn't exist yet (coming soon).
file #1: bad zipfile offset (local header sig): 0
再次感谢！
第二添加： 仍然不正确。
$ cat 1.z01 1.z02 1.zip > combined.zip && unzip -FF combined.zip
Archive: combined.zip
warning [combined.zip]: zipfile claims to be last disk of a multi-part archive;
attempting to process anyway, assuming all parts have been concatenated

它生成了1.wmv，只能在Gnome Mplayer中播放到一半。
第三添加：我错误地使用了7z：
$ 7z e 1.z01
