Diskfern

Diskfern is a native macOS disk space analyzer and cleanup utility that helps you understand what's consuming storage on your Mac and reclaim space safely.

Explore your storage through interactive Treemap, Sunburst, and List views. Find large files, investigate System Data, and discover storage used by applications, Xcode, Docker, development tools, caches, and local AI models.

With 44 Smart Highlights and natural-language search, you can quickly locate files and folders based on their size, type, and other properties.

Diskfern also includes Disk Advisor, an AI-powered assistant that helps explain unfamiliar files and folders by analyzing their metadata. It provides contextual recommendations about what may be safe to remove, what should be kept, and what requires caution.

Review cleanup suggestions with risk labels and move approved items to Trash rather than deleting them blindly.

Diskfern supports macOS 14 Sonoma and later, on both Apple silicon and Intel Macs. Storage analysis stays on your Mac.
