Mac Terminal unzip zip64

Question

I have Mac OS 10.9.5. I have downloaded a large zip file off of the internet that the owner changed to a zip64 for me so it could work. I try unzipping the file with unzip SNPsnap_gcan_3_500.zip but I get the following error

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 SNPsnap_gcan_3_500.zip or SNPsnap_gcan_3_500.zip.zip, and cannot find SNPsnap_gcan_3_500.zip.ZIP, period.

I have no clue how to unzip this file. Any thoughts?

without any installation, comes with the OS.

open a terminal window (e.g. cmd + space -> terminal -> Enter>

enter ditto -xk YourZipfile.zip ./

works.

wouldn't that just copy my zip file to everywherE? – Evan Nov 18 '15 at 18:21

`/` would be root. `./` means the current directory. note the dot! – Markus Nov 19 '15 at 08:20

Thanks! That's the correct tool, `ditto` works just fine and ships with the OS. – Simon Urbanek Jun 17 '16 at 02:06

ditto for whatever reason doesn't appear to have a 'list' option.

If you use 7zip (which can be installed via homebrew,) the 7za binary has zip64 support.

In my case I was trying to extract the Modern.IE Windows 10 VM image...

$ 7za l 'Microsoft Edge.Win10.For.Windows.VirtualBox.zip'  # list zip contents

$ 7za e 'Microsoft Edge.Win10.For.Windows.VirtualBox.zip' # extract

Note that 7za has two different options for extraction, 'e' and 'x'. Only x recreates the directory tree - I got stumped with the very same Windows VM images. – Matthias Winkelmann Mar 09 '16 at 15:08

To install via briew: `brew install p7zip` – Jeff Whiting Jul 18 '16 at 18:16
I'm pretty sure `unzip -l myfile.zip` will list CPIO or PKZip files just fine. – Dan Feb 04 '18 at 20:02
