GUI Tar is a wrapper application which acts as the front end to the 7za, tar, gzip, bzip2, un/compress, unrar, unzip, and zip UNIX utilities. The operating system itself handles the complicated work, while GUI Tar provides a pleasant and easy method to interact with these system tools. GUI Tar is divided into two sections: Extractor and Compressor.

GUI Tar Extractor offers the functionality to uncompress and extract files from archives. The following files can be opened by Extractor: .7z, .tar, .tgz, .tar.gz, .dmg.gz, .svgz, .gz, .tar.z, .z, .Z, .tar.Z, .taz, .tbz, .tbz2, .bz, .bz2, .rar, and .zip.

GUI Tar Compressor can more...

What's New

Version 1.2.4:
  • Improved calculation of file sizes listed in the compression table.
  • Minor UI improvements.
  • Optimizations and clean up for a leaner application.


Mac OS X 10.3.9 or later

Great application, its fast and simple to use along and boots fast, the GUI was simple and easy and clearly states where everything is. the only complaints i have on it is that there are a limited amount of file types you can compress/decompress so i really only use it to compress more then decompress (a good app for uncompressing is The Unarchiver, decompresses almost every single file type there is) . Otherwise this app is worth it :)

One of those great "does one thing and does it well" apps. It makes tars. I need tars. Perfect fit.

This program was so simple and great. EXACTLY what i needed. Zipeg would lock up when trying to unzip large files, and Mac's built in unzip program wouldnt do anything but zip files, so, i came accoss GUI Tar, and it worked perfectly. thanks for the great app. -Justin

(1) This absolute gem works with Leopard (10.5.6 as of this writing).
(2) Though zip and gzip supposedly use the same algorithm (Zempel something-or-other), using gzip GUI Tar consistently makes smaller files, with no apparent speed hit.
(3) Truly a time saver over having to open the Terminal to accomplish an alternative compression to zip; this works fast and slick.
(4) Recommendations for a future version (and ask for some money): (a) a Contextual Menu plugin that offers formats if not compression levels (b) compression levels (fast and bigger, slow and smaller, etc.), could be pre-set in Preferences.

This is a great example of a GUI "wrapper" that is clean, intuitive and in the grand Mac fashion "just works".

I have some backup files that are created from my web sites control panel and have never been able to untar them for some reason.

I have tried StuffIt, BOMArchiver, and even iArchiver and none of them worked. StuffIt and BOMArchiver both gave me errors when trying to do it. When I used iArchiver it didn't completely untar the files. That might have been because the trial had expired and the app quit itself but not sure.

I came across this little gem and it work perfectly and it only took seconds to untar at 280MB file.

Developer: Keep up the good work. Excellent software!!

Thanks for sucha great product. But I am curious.

Why doesn't GUITar also compress files/folders into ZIP format (like all the other multi format archivers)?

That is a good point about the lack of zip compression in GUI Tar.

There are two reasons why zip compression isn't available yet in GUI Tar.

1) The Finder in Mac OS 10.3 (and later) has a Create Archive command, which makes it easy to create zip files. Since a large number of Mac users have at least Mac OS 10.3, most people can already create zip files.

2) Adding zip compression functionality was originally planned for the original release of GUI Tar, but due to some technical problems at the time, it was not added.


I have a question for the developer. Is there a way to compress larger than 4GB with your program? Because every way I have tried it stops at 4GB before completing the compression. I am trying to move a 37 GB folder from an HFS+J drive to a DOS drive (no, I'm not running out of room on either; one is a 1TB HD and one is a 2TB HD, formatted appropriately on both) and have been having problems because of the size of the programs (mostly video files a friend encoded from their video camera travels on their Windows PC). If there is not a workaround or fix with your program, please let me know about a way to do it with the command line or otherwise. Thank you.


I am in the same mood as Tshunter, emaning, wanting to work with large files. He is robably not getting at it cause his drive is probably FAT32. I want to compress the files in smaller pieces so that i can move em and not get horassed by this 4GB limit in FAT32 formated drives to watch downloaded movies on the TV through a pendrive. Compress in pieces and decompress as a whole to the pendrive Hope this GUI does this on the Mac OS.

Forgive my ignorance but I thought if you compressed a file the end product should be smaller in size than the original. This doesn't seem to be the case, so I don't see the point of this application.

Version 1.1

You are correct that the file should be smaller after you have compressed it (using a format such as gz, bz2, Z, or 7z). There are cases where the compression is very small and does not provide for much benefit, especially if the file (or group of files) are already in a compressed format. An example is if you are trying to compress a JPG image, which is already a compressed format, so trying to shrink it even further does not help a ton. However, trying to compress a large text document should have decent results.

The only other way I could see a file increasing in size, is if you only archived it (tar), which just packs a file (or usually, a group of files) into a single file, but it does not compress it.


Usually, people who leave comments similar to yours, are both ignorant and unintelligent. However, they don't know about their own ignorance.

--> Of course, the purpose of compressing files and folders is to make them _smaller_.

I'm sorry to hear that this app didn't decrease the size of your stuff -- however, don't blame this app, GUI Tar is not responsible. Open the Terminal -> write "tar", "zip" or "bzip2" (or whatever type of compression you tried).

GUI Tar is only a wrapper--a Graphical User Interface to these built-in tools.

--> If you have a folder of already compressed files (like zip, tar, gzip -- or mp3, mpg, m4v, jpg and others) you should not expect more free disk space, though.

However, compressing a bunch of folders would usually save you either much or some disk space.

Compressing compressed files is not efficient, and usually only a waste of time and CPU power.

Maybe that's what you did?


To respond to celebritarian's comment, I don't think it was necessary to be so rude and bellitling! Just because someone does not understand one thing does not mean you should just assume that they are ignorant and unintelligent. Would you appreciate such an assumption about you?


The answer of celebritarian was rude, but I think it wasn't due to the commenter ignorance, but the way this guy was bullying the developper in a very pervert way, when it was actually not the fault of the developper...

But I agree there is never any need to be agressive :)
Don't worry, be happy ^_^


Samantha: You wrote that reply rather late, I wrote that comment a long time ago. How you interpret my comment and its tone is your opinion. I hear what you're saying, and I do understand your point.

I give you this: Off course I didn't want to be a big happy smile when replying to a post like that. Personally, I think the most of what I wrote was kind of on-topic and related to his problem/disappointment with the application.

Sure, my comment did contain some sense of humor (at least I tried)... Call it irony. Did you _not_ think I was suggesting a likely answer to why his files didn't get smaller by using GUI Tar?
I think I did.

Thirrouard obviously got the point (the part about me being aggressive was axeggarated, though ;-) I feel quite calm). I wasn't rude without reasons. This is a free app. Some guy (or girl) has put a lot of effort, skills and time in making this a nice GUI to the Unix tools -- like tar.

--> These tools -- like tar -- is in there, behind the beautiful Mac OS X interface. Go to /Applications/Utilities/Terminal.app, once in the Terminal, write: "man tar". All Mac OS X versions have it, deep down.

That's the main concern: The Unix tool tar _works_. GUI Tar is like many other apps, only a GraphicalUserInterface for these tools. That means you can't blame this app for bad compression rates on some random (unknown?) files.

It is free. It uses free tools to do the job the user wants. Don't blame the developer. That's basically what I wanted to say: Millions of applications are available, free of charge, gratis, free, whatever.

Why? Because there are persons who develop great software and makes it available for everybody -- like us -- for free. Personally, I found it very rude to whine about whatever problem you have with an app, which you've obtained for free and which the developer doesn't get a nickel for.

Especially when the developer obviously hasn't done anything wrong. --> Take it or leave it. It's free: If you appreciate it, well, show it! If you don't like it, don't immediately start complaining.


celebritarian - not a developer. ;-)


Well, I don't totally agree.
Free software or not, developers need feedback to improve their software. If you have any real problem, then it's good to let the developer know.
So I think you can complain about things, like bugs, or lack of feature, as long as you say it in a constructive way, and obviously this was not the case here ;)
