Disk Prism - Storage Visualise

When your Mac says storage is almost full, the hard part isn’t deleting—it’s knowing what to delete.

Disk Prism is a native disk space analyzer for macOS. Choose a folder or drive, scan once, then read the same data eight different ways: folders, sunburst, flame, bubbles, mind map, top sizes, age map, and treemap. Find large files, heavy folders, and duplicates without rescanning.

ONE SCAN, EIGHT VIEWS Most disk utilities give you one chart. Disk Prism lets you switch visualizations instantly—drill into a sunburst, compare sizes in a treemap, or spot stale files on the age map. Same walk, different lens.

YOU CHOOSE WHAT TO OPEN Disk Prism only accesses folders and volumes you grant through the Open panel. No Full Disk Access setup. No background snooping. Scanning, hashing, and cleanup stay on your Mac.

INSPECT BEFORE YOU ACT • Size on disk, logical size, and APFS space savings • Creation and modification dates • Largest items inside any folder • Quick Look and Reveal in Finder

RECLAIM SPACE SAFELY Stage files on a cleanup queue, review the list, then move them to Trash—recoverable until you empty it. System paths stay protected. Disk Prism never permanently deletes in the background.

FIND DUPLICATE FILES Content-based duplicate detection within your scanned folder. Files that only share a name are ignored.

COMPARE OVER TIME Save snapshots and diff them against a later scan to see what changed after a cleanup—or what crept back in.
