How to unzip split files on OS X

Question

How do I unzip a split zip file?

In Terminal, I wrote: unzip filename.zip and it did not unzip this file.

Terminal wrote:

$ unzip filename.zip
Archive:  filename.zip
warning [filename.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):  4
file #2:  bad zipfile offset (local header sig):  98
file #3:  bad zipfile offset (local header sig):  471
file #4:  bad zipfile offset (local header sig):  6635222

Double clicking of this file creating filename.zip.cpgz

What can I do?

So, are there any other parts of this file or do you only have this one part? If you only have one, are you trying to get the contents of this part only? — slhck, Dec 07 '11 at 17:12
Have you tried other uncompression tools? I'd run uncompress and gunzip on the file and see if was processed with one of those. — Wilersh, Dec 07 '11 at 20:25
It's no problem to unzip multiple archive using unarchiver.app but I'm looking for the terminal command to do this without of using any apps. — Kris, Dec 08 '11 at 14:16
First I'd take it over to a Windows box and try 7Zip on it. If that doesn't work I'd try to find the rest of the zip file pieces and concatenate them together. — Daniel R Hicks, Jul 20 '13 at 01:00

This was the straight forward and only solution that worked for me on OS X (taken from here).

1. To create a split zip archive (a series of files named zip, z01, z02...), run following command in Terminal:

zip -s 100m -x "*.DS_Store" -r split-foo.zip foo/

2. To extract a split zip archive (a series of files named zip, z01, z02...), run following command in Terminal:

First, combine the split archive to a single archive:

zip -s 0 split-foo.zip --out unsplit-foo.zip

Extract the single archive using unzip:

unzip unsplit-foo.zip

if you have splitted binaries, like file.zip.001, file.zip.002 ... you may just need to combine the files e.g. using `cat` command: `cat file.zip.* > single.zip` – Karl Adler Apr 29 '15 at 09:52
@abimelex your comment helped solve my exact scenario! – Daniel Apt Jun 02 '15 at 11:44

You're the man @abimelex !!!!! - I did have to use [p7zip](https://superuser.com/a/667076) to extract them because of this error: `need PK compat. v5.1 (can do v4.5)` – bryan May 18 '17 at 15:06
I'm glad to help. Since the comment has a lot of up-votes I added it as answer too. – Karl Adler May 19 '17 at 08:16

`zip -s 0 split-foo.zip --out unsplit-foo.zip` doesn't make any sense as a split archive? How would you combine two files into one zip file? – gotnull Mar 16 '20 at 02:03

Just cat all zip files in sequence to a single file and use unzip command on that.

For example:

cat file.zip.001 > s.zip 
cat file.zip.002 >> s.zip
cat file.zip.003 >> s.zip

unzip s.zip

additionally to this answer if you have split binaries, like file.zip.001, file.zip.002 ... you may just need to combine the files e.g. using cat command:

Try to verify the order using `echo file.zip.*`. – U. Windl Jun 04 '23 at 22:54

I hit this issue when trying to re-assemble a large directory downloaded from Google Drive.

Similar to this issue, if you are dealing with a set of zip files that do not include numbered file extensions (foo.z01, foo.z02, etc) and are simply multiple zip files that should be unarchived together into the same directory, the following worked for me:

unzip '*.zip' -d /path/to/unzip/destination

Just run this command on the bash prompt to concatenate the zips.

for i in `seq 1 5`; do cat file.zip.0$i>>uncut-version.zip; done

the above example has 5 parts.

Then unzip the file using your favourite method

unzip uncut-version.zip

Tested on a 10.8.5 Mac OS

Use Stuffit Expander free version
Just drag the last file (the one with .ZIP extension) in Stuffit
Wait for a while because it seeme Stuffit re-build first the complete file
See all your files unzipped

In my case, within OS X 10.11.6, i had a multipart archive with extensions

.z01
.z02
... (etc)
.zip

Using

zip -s 0 in.zip --out out.zip

did get me a single zip. It did not extract with unzip, but did with 7zip, installed via MacPorts:

port install p7zip
7za x out.zip

7-zip worked for me on the original files. No need to zip first... – der_michael Mar 23 '21 at 21:43

What worked for me is very simple: Open the .z01 file with the free Mac application The Unarchiver (available from the Mac App Store). It handles the extraction nicely.

This was the most simple solution I could find:

find ./ -name "*.zip" -exec unzip {} \;

Just Unzip all files using terminal unzip filename001.zip, filename002.zip that will automatically add files in one folder.

in MacOS 10.13.6 High Sierra, working way is to:

cat filename.z01, filename.z02, filename.z03 filename.zip > unsplited_foo.zip

and after that use unzip:

unzip unsplited_foo.zip

NOTE: be careful order of files in cat is matter
