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

  • When I try to trace the problem using "strace unzip filename.zip" the error was, "ERROR: unable to open /dev/log"

I've tried by using some jar/Java utility installed in my server

UNIX-SERVER# find /opt -name jar
UNIX-SERVER# /opt/java6/bin/jar xvf zipped_file.zip
  created: files/
  created: files/install/
extracted: files/install/addLangs.sh
 inflated: files/install/attachHome.sh
 inflated: files/install/clusterparam.ini
 inflated: files/install/detachHome.sh
 inflated: files/install/lsnodes
 inflated: files/welcome.html

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