How to extract and join files xxx.zip, xxx.z01 and xxx.z02

Question

I have three files 1.zip, 1.z01 1.z02. I would like to extract and join them into a 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 it is and how I can solve it?

Thanks and regards!

ADDED: Is my usage of "unzip -FF" wrong? It seems not work:

$ 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

Thanks again!

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:

$ 7z e 1.z01

$ 7z e 1.zip

Answer 1

I have the same issue today with Mass Effect 3. Stupid coders-for-food broke the installation of Mass Effect 3 in new version of origin on windows and my wine of course too (installation hangs on 99%). I have to make manually installation:

cp /mnt/cdrom1/Mass\ Effect\ 3.z01 ~/temp/Mass\ Effect\ 3.z01
cp /mnt/cdrom2/Mass\ Effect\ 3.zip ~/temp/Mass\ Effect\ 3.zip
zip -FF Mass\ Effect\ 3.zip --out Mass\ Effect\ 3.zip.fixed
mkdir Mass\ Effect\ 3
unzip -d Mass\ Effect\ 3/ Mass\ Effect\ 3.zip.fixed
du --total Mass\ Effect\ 3
>> 10466048 (~10.5 GB => success)

zip -FF should be applied to last part of archive, it will automatically check for all parts

Answer 2

According to reading man zip, "Split .zip" archives can be recombined and unpacked using unzip -FF.

Answer 3

Try zip -FF 1.zip --out 1-full.zip

(multipart.. yes)

unzip -FF 1-full.zip

I think most likely some data is broken many times so you need the -FF still in unzip. -F may work also. Worked?

Answer 4

I also had some issues. man unzip said the following:

Also, zip 3.0 and later can combine multi-part (split) archives into a combined single-file archive using ``zip -s- inarchive -O outarchive''.

This (zip -s- vmdkdisk -O combined) seems to work for me... (combine vmdkdisk.z01 and vmdkdisk.zip into one file combined.zip)
