BetterZip lets you quickly view the contents of an archive in a Finder like list view without extracting it. It lets you add files to archives and extract single files from archives.
BetterZip can extract and create fully WinZip compatible AES-256 encrypted zip files. It handles zip, sit, rar, 7-zip, tar, dd, bin, hqx, tgz, tbz2, gzip, bzip2, arj, lha/lzh, cab, iso, chm, rpm, deb, nsis, and cpio archives.
The preview drawer lets you quickly view images, PDF, HTML, RTF, and text files.

Excellent application. First of all it may become a Mac version of WinRAR (thanks to supporting commandline RAR) and native support for creating 7ZIPs is excellent. Unlike Unarchiver it works fine with password-protected RARs and also lets you preview files before extracting. And finally, it works well as unarchiving tool even after expiration.
The best mac archiver I've seen so far.
Might want to give this a try: http://osx.iusethis.com/app/zipeg
It's free, and let's you preview/view files before you extract.
i forgot to mention, the encrypted archive feature, is very useful [as it was on some other archive apps i can remember from the windows days].
I've fallen in love---it was the use of RAR command line files as "Helpers" to compress that won me over. Haven't found anything that can touch this yet.
this is by far the most intuitive and functionally efficient compression application on the mac platform. i just made the switch from pc to mac about a week ago, after trying upwards of half a dozen archiving programs i finally settled on this one and it has proved to be an invaluable addition to the collection of software i have amassed thus far.
Great app, but way too expensive.
I think they would sell more of it (and ultimately make more money) if it were under 10 dollars.
Far and away the best Zip/archive program for the Mac. Compare this to its only competition which is Stuffit Deluxe at $80 and you can agree this is a must-have program.
BetterZip is the "gold standard" in Mac OS zip/archive software with support for more formats and a clean UI. It's truly the WinZip of the Mac platform.
So far, so good. Went looking for a better compression tool when I got tired of waiting for Stuffit to release a Universal Binary, and this is pretty slick so far. Kinda miss having the automation/integration of Stuffit, but this makes up the difference in more options to handle archives, a much more Mac-friendly interface, and not running a series of PowerPC processes in the background. Good times.
this is a great app...i really wish i had purchased this instead of ZipIT! now i'll have to wait until i have some extra $ :(
