I have just uploaded the new version 1.4. After more than 3 months this is a long overdue update. It has some neat, new features, enhancements, and important bug fixes.
The new version can not only strip Mac specific files, e.g., resource forks or Finder settings, from archives, but also arbitrary files. This is particularly useful for removing all version control folders with one click. You can enter your own search patterns using regular expressions (Preferences, tab Cleaning). The patterns for the major version control systems Subversion and CVS are already included.
Extracting single files from zip archives is a lot faster in the new version, especially for larger archives. Until this new version BetterZip had to extract the whole archive in the background, even if you only wanted to view one small file. This is no longer necessary.
BetterZip will now remember your favorite archive format and use it for saving new archives. The new 1-Click-Save function can create archives in one step without asking for a filename, folder, or archive format.
BetterZip 1.4 can now open and extract DEB and RPM archives.
Last but not least, extracting archives is now a free functionality. Of course, in a limited way: You can only extract the whole archive in one step. But that should be good enough, to let other people extract archives that you created with BetterZip, e.g. AES-256 encrypted zip files which include resource forks.
For a complete list of enhancements and bug fixes, please see the version history.
