error: Zip file too big (greater than 4294959102 bytes)

The customer send us the dump for Exadata POC and this dump is unavailable to unzip :

[root@ed01db01 ]# unzip
error:  Zip file too big (greater than 4294959102 bytes)
warning []:  10149171547 extra bytes at beginning or within zipfile
  (attempting to process anyway)
error []:  start of central directory not found;
  zipfile corrupt.
  (please check that you have transferred or created the zipfile in the
  appropriate BINARY mode and that you have compiled UnZip properly)

Our unzip version is:

[root@ed01db01 ]# unzip
UnZip 5.52 of 28 February 2005, by Info-ZIP.  Maintained by C. Spieler.  Send
bug reports using; see README for details.

The solution 1:

[root@ed01db01 ttelek]# funzip > dmp.dmp
[root@ed01db01 ttelek]# ls -l

-rw-r--r-- 1 root   root 65195868160 May 13 11:24 dmp.dmp
-rw-r----- 1 oracle dba  14444138961 May 12 00:03

[root@ed01db01 ttelek]# funzip
fUnZip (filter UnZip), version 3.94 of 17 February 2002
usage: ... | funzip [-password] | ...
       ... | funzip [-password] > outfile
       funzip [-password] > outfile
       funzip [-password] infile.gz > outfile
Extracts to stdout the gzip file or first zip entry of stdin or the given file.

Our conclusion: the Exadata has the funzip by default, we don't install it intentionally.

The solution 2:

[root@ed01db01 ]# zcat > dmp.dmp

Exadata has zcat by default.



  1. i have a 96 gig zip file i cannot extract....
    unzip 5.52.. yum says it is the latest...
    what can i do to extract the file to the current directory???

    funzip > /

  2. I'm having an unzip 6 and a zip 3 (with which the zipfile was made) and it gives EXACTLY the same message.

    On the info-zip site, it says that even lower versions (of which unzip 5.52) do NOT have this limitation.

    When running the ZIP file, I didn't see any error (but I only saw the last page).

    Conclusion : still unreliable, when it comes to large files, even in 2014.
    Note not a lot is said about 64-bit
