CreativeBe has released Rucksack 1.1 (http://rucksackapp.com), an update to its archive and file system tool for Mac OS X 10.6 and higher. Designed by Apple Design Award Winner Dietmar Kerschner, Rucksack lets users open, create and convert archives, as well as split and combine files.

The biggest change in version 1.1 is that users can now open more than one archive at once by dragging the archives onto Rucksack’s main window. Also new is the option to remove archives after opening them, either by moving them to the Trash or deleting them immediately. Plus, there’s now an option to automatically show output files in Finder when Rucksack has opened an archive.

Rucksack costs US$25, though version 1.1 is a free update for registered users. A 14-day demo is available for download.
