BetterZip lets users quickly inspect an archive without first extracting its contents.
Users can add or extract files via drag-and-drop or delete files from archives.
With the click of a button BetterZip can strip Mac specific files and folders, e.g., resource forks or Finder settings, from zip files and tar balls for best compatibility with Windows or Linux systems.
BetterZip currently handles archives with these formats: zip, tar, gzip, bzip2, rar, 7-zip, cpio. It can open Java jar, war, and ear files and various compressed tar formats. More archive formats will be added in the near future.
