Yup. It's here https://www.akeebabackup.com/download/official/akeeba-extract-wizard.html

You're welcome!

There are three major reasons I discontinued eXtract

1. It was written in .NET Framework. Microsoft discontinued it in favour of .NET Core which does not, however, yet support Windows Forms properly. I'd have to learn to use yet another complicated frontend framework. I don't think that's a good use of my time at the moment. Not to mention that there were many loud, rude people who took exception with my decision to use a cross-platform language I can actually write code in for eXtract instead of, dunno, trying to learn Swift and C++/GTK3 from scratch to make macOS and Linux binaries? This was getting to the point where the demands became utterly unreasonable.
2. It cannot handle JSP (encrypted) files correctly. This is an unfixable issue and has to do with the underlying cryptographic library. I would need to use a different crypto library which means yet another learning curve. Again, I don't think that's a good use of my time at the moment.
3. eXtract was written back when people didn't really know they could run local servers on their machines. There was an obscure project called XAMPP and a niche product called WAMPserver. And, of course, UNIX neckbeards. Fast forward to 2020. Local servers are commonplace. Most people are comfortable enough to even use Docker containers. This means that running Kickstart on your computer –either web or under CLI– is a perfectly viable option. This makes eXtract obsolete.

Do you know of any other tool out there that would simply unpack the files? I will check out what you mentioned in your response. 

Why, yes, of course! Akeeba Kickstart ???? The idea is that you already have a web server set up on your machine. Just put Kickstart and the archive in a folder under your server and run Kickstart. It will extract the archive. Just don't press the Run the Installation button.

Remember that Kickstart only extracts the backup archive. It does NOT restore the backup. The archive contains a copy of your files, a database dump and a restoration script called ANGIE. That's why there's the "Run the Installation" button. It takes you from Kickstart (which extracted the archive) to ANGIE (which restores the backup). If you don't press it you have just extracted the backup and that's all there is to it.

You should also check the advanced options at the bottom of Kickstart's page. You can even tell it which files and folders to skip extracting.

Instead of complaining why don't they consider helping with solutions/support? 

Those who can, do. Those who can't do, teach. Those who can't teach spew ignorance on every comment section on the Internet. (This is not mine, I paraphrased it from someone else).

I'm glad I had the opportunity to tell you about Kickstart :)

Yeah, I stopped paying attention to moaners. I understand how they tick. They don't feel in control of their life and they try to exert control on someone else. They need a therapy. I have neither the time nor the skillset to be their therapist so I just block and ignore them.
