Settings – Archive Types

The Archive Types tab decides which archive formats BetterZip should claim as default opener in the Finder. The bundle understands many more formats than it claims; you choose which ones you actually want associated with BetterZip.

For a full catalogue of what BetterZip can read and write, see Supported Formats.

The Formats Table

Each row is one archive format BetterZip can handle. The checkbox in the first column controls whether BetterZip registers itself with macOS as the handler for that format’s file extensions. Check it to make BetterZip the default; uncheck it to release the association.

When you turn off a format, BetterZip remembers what the previous handler was and restores it. Turning the format back on later re-claims it: useful if you’ve experimented with another archiver and want to go back.

The Handle All and Handle None buttons flip every row at once. Use Handle None when troubleshooting Finder file-type associations, then re-enable just what you need.

Archives That Aren’t Archives

Files with these extensions will not be treated as archives
Some files are technically archives but you’d rather BetterZip leave them alone: .docx, .pages, .jar, and other container-based formats are the typical candidates. List their extensions here (comma-separated, without leading dots) and BetterZip will skip them when it would otherwise auto-open or auto-extract them.
