I have these three files: 1.zip
, 1.z01
and 1.z02
. I would like to extract and join them into a single file, by right clicking 1.zip
and selecting Extract Here. But then there comes an error:
7-Zip 9.04 beta Copyright (c) 1999-2009 Igor Pavlov 2009-05-30
p7zip Version 9.04 (locale=en_US.utf8,Utf16=on,HugeFiles=on,2 CPUs)
Error: /home/tim/Desktop/1.zip:
Can not open file as archive
Errors: 1
I was wondering what the problem is and how I can solve it?
ADDED:
Is my usage of unzip -FF
wrong? It seems not working:
$ 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
2nd ADDED:
Still ain't right:
$ 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
together in order. Expect "errors" and warnings...true multi-part support
doesn't exist yet (coming soon).
warning [combined.zip]: 209829313 extra bytes at beginning or within zipfile
(attempting to process anyway)
file #1: bad zipfile offset (local header sig): 209829313
(attempting to re-compensate)
extracting: 1.wmv bad CRC ee181eef (should be f3c61875)
It generated 1.wmv
, which can play well only until midway in GNOME MPlayer.
3rd ADDED:
Am I using 7z
wrongly?
