The Unarchiver

By Dag Agren

Open the Mac App Store to buy and download apps.


The Unarchiver is a small and easy to use program that can unarchive many different kinds of archive files. It will open common formats such as Zip, RAR, 7-zip, Tar, Gzip and Bzip2. It will also open many older formats, such as StuffIt, DiskDoubler, LZH, ARJ and ARC. It will even open other kinds of files, like ISO and BIN disc images, some Windows .EXE installers. The list is actually much longer - see the program homepage for the full list.

The Unarchiver also tries to detect and correctly handle the filename encoding in the archives it opens, allowing you to open files from every part of the world without getting garbled filenames.

The Unarchiver aims to be the only unarchiving program you will ever need, and to stay out of your way.

However, if you want to browse the contents of archives, or if you want to support development of The Unarchiver, look for "The Archive Browser" on the Mac App Store, or go to! It lets you browse and preview archive contents, and find out information about archives!

Also, if you need to open archives on your iPad or iPhone, look for "Archives" on the App Store, or go to It is based on The Unarchiver, and lets you easily handle Archives on iOS!

What's New in Version 3.9.1

* The Archive Browser for Mac OS X and Archives for iOS have also been updated! Look for them in the App Stores!
* 3.9.1: Fixed extraction of double-format archives like .tar.gz, which was accidentally broken in 3.9.
* Add Dutch translation.
* Add support for PMA files.
* Better support for broken Zip files.
* Fixed bugs in handling of NSIS and MSI files.
* Fixed a bug where minimizing the window could make it remain open after extracting.
* Tiny interface tweaks.

Good bye Stuffit Expander

I used Stuffit Expander for years and never really though much about it. Then one day I saw an article that mentioned The Unarchiver and how great it was. There is nothing fancy about a file expander. If it opens the file, it has done it’s job; but I figured I would give The Unarchiver a try because Stuffit Expander hasn’t been updated in years.

Several times I have downloaded crupted archives that are split into multiple files. — Stuffit Expander’s progress bar only shows for the first file in the archive. If you open a four part archive with Stuffit Expander, the progress bar would be full after reading the first file in the archive and then just sit there until the error accured. — The Unarchiver’s progress bar shows the progress of the whole archive decompression. If you open a four part archive with The Unarchiver and the progress bar is at 3/4, and then it reports an error… obviously the error is in the fourth file. With The Unarchiver If there is an error in an archive, you have a idea of at what point the error accured and which file to redownload. That sold me. It’s a little thing, but a big time saver.

Thank you

I just downloaded a `.sfx` file, which not of the system utilities could handle, so I had to find something.

First I tried StuffIt Expander, who required that I sign up for their emails to download, and the `.dmg` file they provide is packed with promotionals, that I feared to be ad-ware. Mac is pretty good about not letting ad-ware install when you drag-drop an application in, so I went with it. It wouldn’t even extract what I needed.

Next I found the Unarchiver, who unlike StuffIt, doesn’t push for an upsell I don’t need, doesn’t charge, and doesn’t package with ad-ware. And, most importantly, it opened my `.sfx` archive. I already donated to the developer.

One of the great unsung heroes of the App Store

The Unarchiver is an app that I rarely think about or even realize is helping me throughout the day. But after switching to a new Mac and finding myself trying to uncompress several files without it, I immediately realized how handy it had been for me without me even noticing. The fact that the app doesn’t ever announce itself or get in the way of my workflow as it’s doing its job just makes it even better. I can’t thank this developer enough for the work he’s done creating this frequently-used and immensely useful utility.
