* On Mountain Lion, you can store archives on iCloud and share them with other Macs and iOS devices using iUnarchive for iOS *

With iUnarchive, you can create, modify and open archives. Instead of cluttering the disk with files, you can preview and open files directly from within iUnarchive. Only files selected for preview and extracted files are actually uncompressed.

Please note: extracting files with iUnarchive replaces existing files with the same name in the same folder.

If an archive contains another archive, you can choose to open the nested archive with iUnarchive.

Archives that can be opened by iUnarchive include zip, rar, 7-zip, tar, gzip, bz2/BZip2, LhA and StuffIt, including password protection for zip, 7-zip, rar and multi part rar.

Archives of type zip, jar, war, ear, cbz, 7z, tar, tar.gz and tar.bz2 can be created and updated.

Files opened from within iUnarchive using the 'Open with' option that have been edited can be updated back into the archive. iUnarchive will detect the changed files and present the option to update the files.

Files can be added or extracted with iUnarchive using drag and drop from or to the Finder.

iUnarchive uses the Quick Look framework to preview files. File types that can be previewed in iUnarchive include JPG, PNG, GIF, XLS, DOC, PPT, PDF, RTF and iWork (Pages, Numbers and Keynote) files, but also a large number of text files and programming language source files which use syntax highlighting. Supported types include c, h, cpp, hpp, cs, html, css, js, java, php, py, rb, sql, xml, xsl and wsdl, depending on which Quick Look plugins are installed.

Slightly slow processing for larger archives

It works fine, and it does it’s job. It has a clean UI and every small feature you would expect in an unarchiver. The only thing I’ve noticed as of yet is that it takes a minute or two to open larger archives (In this instance, 8GB zip),but other than that it works great! Worth what I paid for it!

I haven't fully explored the app yet, but so far it is terrific. The developer needs a writer to really explain and market this app.
The interface allows you to see the contents of a zipped or compressed file. Great for checking the contents before sending it out to a printer or client. You can look inside an inDesign package and review fonts, Photoshop and Illustrator files, etc. —not the inDesign file unfortunately—and preview and confirm that all is correct. It could be your own, or that of a co-worker if you are in production.
With incoming files, you can confirm what's inside before you uncompress them—ideal if you need to monitor for content, or available hard disk space. If it contains a PC file, I know that I won't be able to open it without Parallels or that it might have a virus or macro.
Finally, the app's interface allows you to choose the default application to do your unzipping, decrunching, whatever—you will have to have some of these apps in the first place. The app is a conduit of sorts. I'm just using the app as a screener and so far, it's doing an excellent job.

A must-have app!

This is a very helpful app that is one of those apps that I'd recommend to anyone: It's immediate, and gets the job done without any fuss (there are a few obscure file extensions that I've run into that it can't unarchive though).
