Disk Map - Visualize Hard Drive Usage & Free Space for Mac

Full-picture view of your storage

Disk Map gives you a clear, overall snapshot of what’s taking up space on both internal and external drives. It highlights folders and individual files that contribute the most to clutter so you can make informed cleanup decisions faster.

Visual treemap for faster cleanup

The app converts scan results into an easy-to-read treemap, using size-proportional blocks to represent folders and files. That visual layout makes it simple to spot large items you may want to compress, move, or delete, helping you free up significant storage quickly.

Scanning process and polished interface

Disk Map scans connected storage devices to assemble the tree visualization. Its interface is optimized for high-resolution displays, improving clarity and making navigation smoother when inspecting drive contents.
