Diskfern helps you understand what's consuming storage on your Mac, find unnecessary files, and reclaim space without guessing.
Explore your disk through three visualization modes: Treemap, Sunburst, and List. Find large files, investigate System Data, and identify storage consumed by developer tools, Xcode, Docker, caches, build artifacts, and local AI models.

- 44 Smart Highlight Categories: Find developer caches, build artifacts, logs, temporary files, and other storage clutter.
- Natural-Language Finder: Search using everyday queries such as "videos larger than 1 GB" or "PDFs from this month".

- Disk Advisor: Get on-device explanations of unfamiliar files and cleanup candidates using Apple Intelligence on supported Macs.
- Guided Cleanup: Review candidates using Safe, Review First, and Protected classifications before moving approved files to Trash.
- Collector: Gather and review cleanup candidates together.
