For Mac OS X
Guides on emulating older applications

7zX version 1.7.1 is an archive creation/extraction tool based on 7-Zip. For Mac OS's 10.4+


Built for all Macs
All components included in 7zX are Universal Binaries; they are designed and built to provide the best possible performance on Apple’s new Intel based Macintosh computers. As with all Universal Binary software, 7zX is also compatible with older PowerPC based Macs.

Resource Forks, Spotlight Metadata
The Mac OS stores important informations such as icons, creation/modification dates, type and creator, user privileges and Spotlight metadata in a particular construct, named resource fork. 7zX can preserve these informations, archiving them together with regular data in 7z archives.

Self-Extracting Archives
When sending data, it is essential to make sure that every user capable of receiving your files will be also able of opening them. 7zX is capable of create self-extracting archives, compatible with any Macintosh running Mac OS X 10.3 or higher.

Password Protection, Powerful Encryption
The ability to handle password-protected archives has been only recently introduced in 7zX, but certainly represents a welcome addiction. The 7z archive format supports Aes-256 encryption, approved by NSA to protect classified Top Secret information.

Segments/Multi-volume archives
With 7zX, it is possible to divide large archives into smaller segments, or to join such segments to recreate the original file. Typically, this becomes useful when you have to store a huge file or folder using CDs/DVDs, or to work around attachment size limits most providers impose.

Cross-platform solution
Being based on the excellent open-source project 7-Zip, this software can create archives compatible with any popular operating system, such as Windows, Linux, and Mac OS. But that’s not all: even less common operating systems, such as BeOS or FreeBSD, are supported!

Excerpt: From enclosed PDF documentation.

Originally hosted here: 7zX (Web Archive mirror).

Similar Software: Keka

Like Keka, 7zX is an OS X GUI frontend wrapper to the command-line version of 7-Zip.

Architecture: PPC x86 (Intel:Mac)

Mac OS X Universal Binary

Tested working OK in Mac OS 10.4.11 (Tiger PPC & Intel) and 10.6.8 (Snow Leopard).

Further tested by 24bit as working in Mac OS's up to 10.14.6

Note: This software wants to phone home when it is used (always?). The site it tries to reach is no longer valid. This behavior can be turned off in a firewall such as Little Snitch.

The resource fork will hardly be preserved upon expanding a file on Windows with 7z.

@24bit: Not much different than classic MacZip or OS X's .zip's, then Wink

I'm going to test this out further and take some files it creates to a Windows machine and see what gives. Interesting to discover Keka reassembled 7zX's files OK on a Mac, so that's encouraging.

@Jatoba: I agree not ideal, but it's just another compression option that should be considered. For example there may be some rare Mac software on WinWorld archives that can be moved here without alteration (all of their archives are packaged as .7z, for good or for worse). But anyway, I can't see the .7z format overtaking Mac OS X' anytime soon, as being the most commonly used of the (bad) compression formats in posting up classic Mac archives to the MG Tongue

And you are right, 7zX is a good one to have for PPC Tiger. It's a keeper for me, too.

I think both .7z and even .zip are not ideal for the Garden, even when the resource fork is preserved, because it can be quite confusing. OS X apps are fine, though. Just my 2 cents, of course.

I like this app because it's another PowerPC 7Zip alternative, when there aren't too many, and Keka's PPC version is faulty.

Good thought Mike.
Yes, I saw the app trying to connect to some server.

@24bit: I would have thought .7z would have been an option already. But it can easily be added.

Good to know that it runs all the way up to 10.14.6

Did you notice that it also wants to phone home (to a now dead link)? Firewalls are your friend with this one.

I'm also wondering about the resource fork bit. It's fine if you're archiving for your own archives, but if uploading them elsewhere would the receiving end be able to reconstruct them without also having 7zX on-board?

Good catch Mike! A compression app aware of resource forks is a good addition.
Maybe time to add 7z as option for uploads?
The app is working up to 10.14.6 Mojave.
Another victim of Apple´s decision about phasing out 32bit apps. Cash

Never heard of this one before, really interesting find!
