If you need to zip or unzip files on a Mac, you could just use macOS’ own Archive Utility. However, while that will compress and de-compress files, that’s all it does. It won’t, for example, allow you to password protect zipped archives, nor does it support many file types. If you want to open RAR archives, for example, you’ll need to use something else.
BetterZIP, available in Setapp, has both those features and many more. It allows you to add comments to archives, delete files from archives without unzipping them, and it’s fully AppleScriptable so you can integrate it into your workflows. It will suggest passwords for you to use to encrypt archives, and you can tell it to automatically trash archives once you’ve unzipped them.
Launch Setapp, search for BetterZip and click Install. Answer the questions in the dialog boxes when BetterZip launches, specifying whether you want to use the menu bar item or drop bar.
One of the best features of BetterZip is the ability to encrypt archives when you create them. To set it up, open Preferences and click on the Presets tab. With Clean and Zip (the option you’ll probably use most often) selected in the Q and T columns, go to the Encryption method menu and select ‘Strong.’
If you want to use the same password for every archive, type it in the box beneath. If you’d rather choose a password when you create an archive, leave the box blank. Close Preferences.
Once you’ve extracted archives, you might find you have a rather cluttered Desktop – if that’s where you choose to extract them to. Declutter, available in Setapp, will fix that for you. It will organize your Mac's desktop for you and make it neat, allowing you to create color-coded smart folders. It can even do it automatically, following rules you set up. If you need to rename files you’ve extracted in large batches, turn to Renamer, also available in Setapp, which makes it really easy to do just that.
