I have a zipped file (using Winrar) and the size of it is more than 4GB from Windows 10. I've already dumped the file in Unix Server and I want to unzip the file but the error always shows:
Code: unzip filename.zip
unzip: cannot find or open filename.zip, filename.zip.zip or filename.zip.ZIP.
Note that the zip file contains .csv files (more than 50 files)
Kindly help me. Thanks
The question asks about unzipping a file which is larger than 4Gb, that was created using Winrar.
According to some people, unzip (Info-ZIP) is not able to handle that large a file due to limitations in the zip-format, and that a multi-volume zip archive would be needed, while others mention a zip64 extension which may/may not be provided in a given copy of unzip:
Now... Info-ZIP has had support for "large files" since the release of 6.0 in April 2009, based on a description in PKWARE, e.g., quoting from Info-ZIP's proginfo/ziplimit.txt file:
A2) Hard limits of the Zip archive format with Zip64 extensions: In 2001, PKWARE has published version 4.5 of the Zip format specification (together with the release of PKZIP for Windows 4.5). This specification defines new extra field blocks that allow to break the size limits of the standard zipfile structures. This extended "Zip64" format enlarges the theoretical limits to the following values: Number of entries in Zip archive: 16 Ei (2^64 - 1 entries) Compressed size of archive entry: 16 EiByte (2^64 - 1 Bytes) Uncompressed size of entry: 16 EiByte (2^64 - 1 Bytes) Size of single-volume Zip archive: 16 EiByte (2^64 - 1 Bytes) Per-volume size of multi-volume archives: 16 EiByte (2^64 - 1 Bytes) Number of parts for multi-volume archives: 4 Gi (2^32 - 1 parts) Total size of multi-volume archive: 2^96 Byte (16 Ei * 4Gi) The Info-ZIP software releases (beginning with Zip 3.0 and UnZip 6.0) support Zip64 archives on selected environments (where the underlying operating system capabilities are sufficient, e.g. Unix, VMS and Win32).
and one can see if it is supported:
$ unzip -v

Now... WinRAR has had support for extracting from zip64 files for some time (version 3.50 in 2005), mentioned in its release notes. But none of the subsequent releases mention zip64, and several people comment that it cannot create zip64 files. If that is correct, OP may actually have an RAR file, which would not be read correctly by unzip.
When unzip attempts to open a file which is not actually a zip-file, it gives a message, e.g.,
$ unzip -l foo.zip
Archive: foo.zip
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.
unzip: cannot find zipfile directory in one of foo.zip or
foo.zip.zip, and cannot find foo.zip.ZIP, period.
In a quick check, if it tries to open an RAR file, the message is the same.
But the file program can tell what it is:
file foo.zip foo.zip: RAR archive data, v5
The 7-zip program can extract an RAR file. But unzip cannot.

G.no_ecrec can be set either way, not only as you state.

G.no_ecrec is set, yes, but that doesn’t happen if the file doesn’t exist.

I've tried by using some jar/Java utility installed in my server
UNIX-SERVER# find /opt -name jar
/opt/java6/bin/jar
/opt/java6/bin/IA64N/jar
/opt/java6/bin/IA64W/jar
/opt/java1.5/bin/jar
/opt/java1.5/bin/IA64N/jar
/opt/java1.5/bin/IA64W/jar
/opt/java7/bin/jar
/opt/java7/bin/IA64N/jar
/opt/java7/bin/IA64W/jar
UNIX-SERVER#
UNIX-SERVER# /opt/java6/bin/jar xvf zipped_file.zip

That works to me, I hope works for you to. Regards
