Bug#661956: unzip fails on 5.4GB ZIP with extra bytes at beginning or within zipfile
The suggested zip command -FFv appears to have fixed the problem zipfile. The resulting fixed.zip works fine with unzip -l. Here is what it printed, with filenames redacted consistently (when the same filename shows up twice it's been replaced with the same string). $ zip -FFv foo.zip --out fixed.zip Fix archive (-FF) - salvage what can Found end record (EOCDR) - says expect single disk archive Scanning for entries...

Thanks for the report. I've just forwarded it upstream: http://www.info-zip.org/phpBB3/viewtopic.php?f=7t=385 but as you point out in the second email, it is likely to be a bug in whatever implementation was used to create the zipfile, in which case there is nothing I could do about it. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#661956: unzip fails on 5.4GB ZIP with extra bytes at beginning or within zipfile
Package: unzip
Version: 6.0-5
Severity: important
Dear Maintainer,
unzip fails on a 5.4GB zip that Windows Explorer and Mac OS Finder can open
just fine. The extra bytes value is just slightly off from filesize-2^32
so presumably this is a 32-bit problem.
% ls -l foo.zip
-rwxr-xr-x 1 andy mts 5488800253 Mar 2 12:49 foo.zip
% unzip -l foo.zip
warning [foo.zip]: 1193830510 extra bytes at beginning or within zipfile
(attempting to process anyway)
error [foo.zip]: 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)
Selected extracts from hd foo.zip with filenames redacted:
