Unzip 5GB zip file

Question

I have here 5GB zip file but I have no idea how to unzip that.

I tried:

7z x file.zip 

Returns: Error: Can not open file as archive

jar xvf file.zip 

Returns: jar: error opening file.zip for reading: Value too large for defined data type

unzip file.zip 

Returns:

End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
note:  file.zip may be a plain executable, not an archive
unzip:  cannot find zipfile directory in one of file.zip or
        file.zip.zip, and cannot find file.zip.ZIP, period.

The file does seem to be a zip archive:

$ file file.zip
file.zip: Zip archive data, at least v1.0 to extract

Any idea?

Thanks.

Solution

The file does indeed appear to be a zip archive. I have no idea why you're getting this problem. It sounds like a limitation of unzip but that, again, is very unlikely. Anyway, one possible workaround is to use zcat instead. However, this will only work as expected if the compressed data is a single file, not a bunch of files and directories:

zcat file.zip > file.unzipped

The other option of course is that the file is either corrupt (you say it's not in your comment but give no evidence to support the claim) or part of a larger archive. Without more information about the file itself we can't help.

@LnxSlck: how to do a checksum? I'm Ubuntu newbie, can you please help me? The other things I tried when unzip file.zip didn't work.

@steeldriver: file.zip: Zip archive data, at least v1.0 to extract

This has been answered before here: askubuntu.com/questions/54904/…

@LnxSlck: this topic I've read before, but doesn't solve my problem. Archive isn't corrupt and it is .zip archive. I don't understand point 3, but it's full archove, not only a part.

@LnxSlck there's no answer there. The OP has already tried all the solutions suggested, they're right there in the question.

do you know who made it? Because... I would assume there might be a 2nd file (and more) to make up the complete file.

[LnxSlck]

Maybe this is file belongs to a serie of files for example 1 of 3 files. What file is it? Have you downloaded it from the internet?

[pavel]

Done, I've just downloaded the zip file once again, and unzip works. First time, the file was probably corrupt, now everything is okay.

[pavel]

it returns gzip: file.zip has more than one entry--rest ignored - in the archive, there are more files, not just one (if I understood well error message).

[terdon]

@panther yes, that makes sense. It was a long shot. Are you sure this is not just a single piece of a larger archive? Where did you get the file from? What makes you so sure it's not corrupt?

[pavel]

yes, I'm sure it's complete and not corrupt archive, because on Windows on the other computers in the past we opened similar files regularly (it's a partional backup of e-mail data). This zip file was created with the same bash script on server.

[terdon]

@panther that does not mean its not corrupted. Can you open this particular archive on Windows? A file can be corrupted when you transfer it between computers for example. Or when something changed while the archive was being created.

[pavel]

No, I have no chance to try to open this file on another computer :-(

[pavel]

I tried to download that once again from server and it works. There probably has to be any error during downloading the file first time. Now, unzip works fine.

[terdon]

@panther ah, there you go. Makes sense :)

I didn´t expect it can download incorrectly, and it was first time I tried to unzip that on Ubuntu. I´ve never have similar problem before, so I didn´t suppose the problem could be here :-).
