When i try to unzip the patch file p14285344_111164_Generic.zip for 220.127.116.11.4 on Linux x64 i get the following message
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 p14285344_111164_Generic.zip or
p14285344_111164_Generic.zip.zip, and cannot find p14285344_111164_Generic.zip.ZIP, period.
The other files making up the 18.104.22.168.4 release unzip ok.
I've seen this issue with other patch files for different releases.
