The Unarchiver v1.6.1
The Unarchiver is a much more capable replacement for "BOMArchiveHelper.app", the built-in
archive unpacker program in Mac OS X. The Unarchiver is designed to handle many more
formats than BOMArchiveHelper, and to better fit in with the design of the Finder. It can
also handle filenames in foreign character sets, created with non-English versions of
other operating systems. I personally find it useful for opening Japanese archives,
but it should handle many other languages just as well.
It is very simple to use and install - simply copy it into your Applications folder or whereever you prefer, and then set archive filetypes to open using it. This can either be done the usual way, or by double-clicking the icon to show The Unarchiver's preferences.
Supported file formats include Zip, Tar-GZip, Tar-BZip2, Rar, 7-zip, LhA, StuffIt and many other more or less obscure formats. Support for so many formats is achieved by using the libxad unarchiving library.
The Unarchiver requires Mac OS X 10.3.9. There is a Google Code page for The Unarchiver, where you can report and track bugs.
New in 1.6.1:
- Leopard compatibility fixes.
New in 1.6:
- Fixed a bug that caused password-protected Zip archives to fail to extract.
- Added support for zip archives created by ZipIt.
- Added a Dutch localization by Jonathan.
- Fixed a rare RAR bug, and some GUI quirks.
New in 1.5:
- Fixed a bug that made it impossible to use The Unarchiver together with Xee on some computers.
- Added a Traditional Chinese localization by NitocTaiwan.
New in 1.4:
- Experimental support for Mac OS X 10.3.
- Support for pax archives, as found in Installer packages.
- Fixed a bug where large archives with lots of resource forks would cause massive memory use.
- Fixed some timezone-related bugs. Some format may still have problems getting the timestamps exactly right, however.
- Various other minor bugfixes.
New in 1.3:
- More localizations: Portugese and Russian. Thanks this time go to Nylson Coelho and Michael Krekin
- Changed the modifier key for extract-to-foler: Either Shift or Option works now. Command was too easy to accidentially trigger when opening a file with Command-O.
- Fixed a bug where app bundles in StuffIt files would not run correctly after being extracted.
- Fixed a bug where The Unarchiver would hang when trying to extract particularly broken files.
- Fixed a bug where apps would be launched when the open-after-extracting option was on.
New in 1.2:
- Added several localizations: Japanese, German, French and Spanish. Many thanks to E-WA, Christoph Schmitz, Thomas Steffen, Thomas Didrel, and Oscar A. Mata T. for their work on this!
- Added an option to have The Unarchiver ask for a destination folder. Holding the command key while double-clicking an archive will also make The Unarchiver ask for a destination folder.
- Fixed many unarchiving bugs. Several problems with Zip files fixed, and SIT files should now work much better, especially on Intel machines.
- Fixed some other bugs in the interface, such as some problems with the filetype association list.
New in 1.1:
- Added options to automatically open extracted folders, and to automatically delete archives after extracting.
- Added an option to select which folder to extract to.
- Fixed the bug where the window would sometimes open below others.
- Fixed a number of extraction bugs.
