BetterZip allows you to create presets for creating and extracting archives. Presets collect all settings that can be applied to an archive, from the destination folder and archive format, to passwords and even a script to execute after the operation completed.

BetterZip can filter out unwanted files during archive extraction. No more Thumbs.db and other unwanted stuff from other systems! It can also prevent files from being put into your archive in the first place. You don't want your hidden version control folders or backup files in the archive.

BetterZip can be scripted using AppleScript. Integrate it in your workflows.
