If you're facing problem while unzipping file of more than 2GB, and if it gives the following error:

Archive: ZIPFILENAME.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.
note: ZIPFILENAME.zip may be a plain executable, not an archive
unzip: cannot find zipfile directory in one of ZIPFILENAME. or
ZIPFILENAME.zip.zip, and cannot find ZIPFILENAME.zip.ZIP, period.

Download and install the rpm @ http://koji.fedoraproject.org/koji/buildinfo?buildID=32620
or download it here.
Now try unzip.
