[!NOTE] Why can’t RAR archives be created? RAR is a proprietary RARLAB format: its compression can’t be included in other software without a commercial license. Archiva supports reading, extracting and decrypting it, and with Convert to Another Format… you can turn a RAR archive into 7z or ZIP.

Inspecting Apps and Packages

Beyond ordinary files, Archiva understands the structure of typical Apple bundles:

Apps (.app): icon, bundle ID, version and build, signature, notarization ticket, Mac App Store receipt and architectures (Apple Silicon and Intel).
Installer packages (.pkg, .mpkg): in-memory reading of the index, with components, installed size and install location.
Frameworks, extensions and plug-ins (.framework, .appex, .plugin, .bundle and similar): version, architectures and macOS compatibility.
