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?

$ 7z e 1.z01

Try:

zip -FF 1.zip --out 1-full.zip
unzip -FF 1-full.zip

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

Put all your zip files in the same directory: zip_file.z01, zip_file.z02, zip_file.z03, ..., zip_file.zip

In Zip 3.0 version the following commands worked for me:

$ zip -s- zip_file.zip -O zip_file_full.zip
$ unzip zip_file_full.zip

As noted in the comments, using a - sign after the command line option -s joins all the zip files together and writes it as a single zip file which you can then extract using the unzip command.

I have the same issue today with Mass Effect 3. Someone 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

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)

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

Above solution by kmario23 is correct I see some typo errors. Here is another example.

    pramodimac:SDK pramod$ pwd
    /Users/pramod/Downloads/SDK
    pramodimac:SDK pramod$ ls -ltrh

Go to the directory where the archives are, through terminal.

If they are on desktop, command is:

cd ~/Desktop

~ is your home folder name. Create full archive, by using this command:

zip -F (name of last part of archive, which will end with .zip, not .z0X) --out (desired output name of compiled archive, if has spaces put " marks around the name).zip

Full archive is now created.
Unpack the full archive, by using this command:

unzip (full archive name, with " marks around it if has spaces).zip -d (destination folder directory, see first step)

It appears 7zip doesn't support multi-volume ZIP archives.

Igor Pavlov states it in this forum thread

Keep in mind that if your follow up files (01, 02 etc.. ) are created by Windows (Z01, Z02 etc..) your linux will not find them. You need to rename the files to z01, z02 ..
