What is Reddit's opinion of Info-ZIP?

From 3.5 billion Reddit comments

Il y a Jean-loup Gailly qui a écrit la compression zip d'info-zip, pas forcément très connu mais utilisé par la plupart des archiveurs gratuits et des logiciels qui affichent du PNG.

>Though why hasn't upstream picked this up?

The Debian bug was forwarded upstream in 2013, as the debbug comment thread states, and the header shows Forwarded to http://www.info-zip.org/phpBB3/viewtopic.php?f=7&t=419\).

The upstream page is down and rotten, so we will never know why they didn't ship a new release with it. But that falls on upstream.

Info-ZIP's purpose is to provide free, portable, high-quality versions of the Zip and UnZip compressor-archiver utilities that are compatible with the DOS-based PKZIP by PKWARE, Inc.

It's the "zip" and "unzip" command on Linux.

So... reading the unzip man page (yes, my search bubble is so well configured that I could actually google "unzip man" and not get porn), it notes that it can handle wildcards itself, though they need to be quoted if they shouldn't be handled by the shell.

This is because unzip will only accept one zip, and treats all other filenames as a "list of archive members to be processed".

So, this should work for unzip:

unzip "*.zip"

This, however, should work in general:

for archive in * do unzip "$archive" done

I use pkzip, and have since the 80s, for file compression. I don't know if you can download it for free anymore. Works like this:

pkzip -add archive.zip .

And boom, you're done.

7zip is probably your best bet if you want a GUI, though.

Edit: Also, check http://www.info-zip.org

A linux/linux-like server? the unzip unzip command is your friend here.

unzip yourbackupFile.zip -d /some/path/to/your/server

note: this requires the ability to ssh/telnet/some-other-wau-to-get-to-a-command-prompt. If you only have FTP access then it's a different story.

note: Unless the bachup is *.gz or *.tar.gz then it's a bit different.

There is a python script available called zipinfo that will analyze zip files. If you're using windows you'll need to install python and run its intepreter for the file.

This is the zipinfo documentation page: http://www.info-zip.org/mans/zipinfo.html

I can't help you regarding its usage as I don't fully understand it myself.

Another, more familiar python user, particularly with the Linux OS would be your best hope from here.
