Designed for OS X
Entropy has been designed specifically for your Mac. It supports OS X specific technologies like extended file attributes and resource forks, which are often missing in other archives.
Equal attention has been paid to aesthetics, usability and technology while developing Entropy.

High Performance
Entropy directly reads and writes archives, unlike most other archivers for Mac which are simply "front-ends". The end result is that Entropy is often discernibly faster.

Ratings and Reviews


Albo Baggins

Reliable, powerful and intuitive. This app offers me all that I need for archiving and unarchiving files. It processes a wide variety of file types with ease. Finally, I like the interface which is clean uncluttered and appealing to the eye. To date I have had no issues with this app and would not hesitate to recommend it.

Really good archive manager for your Mac


If you have a need to archive, unarchive, browse large archives and extract only one file etc - this tool is absolutely irreplaceable (and it looks good too)!
After years of using The Unarchiver + Keka + tar xzf , I came to my senses and forked out for this one. Don't get me wrong those are really good tools (and free). But this one is just better.
Oh, and did I mention that after contacting their support over some small issue I got reply so fast that I didn't have time to finish my coffee? Well, true story.

Powerful, Smart & Slick


Entropy is a slick archive app that can be an unarchiver utility that runs in the background much as the default OSX unarchiver does. However when it comes to archive creation this app has it all. I don't know why there's not screenshots of the options for this app as some of it's true power, to me, is hidden in there such as:
This app has file filtering abilities to screen out unwanted files such as .svn or ._ files from being added to archives.
I really like the presets - you can have as many as you like with options such as encryption password (optional), compression amount, split files and destination folder all preconfigured so they're (almost) a one-click process.
You can set CMD key to toggle Entropy's response when you double click an archive - so instead of just unarchiving immediately it will open the app so you can browse the contents with quick look (spacebar). In fact it has the same file/folder navigating keyboard shortcuts as Finder.
You can also delete files/folders from archives and re-save the archive without creating a new archive.
The reason I've only given it 4 stars as the one thing you can't do (yet as I've brought this up with the developer) is drag a bunch of files to the dock icon and it spring into action. It does respond to an archive being dropped onto it, but not files you want to create a new archive with.. this feature is coming though.
If you like the sound of the app may I suggest you grab the 15day demo and try it out.
