Open archives
You just received an email attachment you can't read? You just downloaded a file you can't open?

With Rucksack you can open all the popular archive formats from RAR over StuffIt to 7zip, and of course Zip.

To open an archive, simply drag it onto Rucksack's dock icon.

If you only want to open some of the archive's content:
  1. Download and launch Rucksack
  2. Click Extract
  3. Drag in the archive you want to open
