ExactDisk01 / DEVELOPERS
ExactDisk
Choose it to connect supported toolchains and generated artifacts to projects, understand classifications, and use a tightly scoped, revalidated Trash workflow.
ExactDisk / A different view of your Mac
A disk map shows where. Developers also need to know why.
DaisyDisk and PocoDisk help you explore storage through visual disk maps. ExactDisk is built around developer projects, toolchains, and knowing when a generated artifact is safe enough to move to Trash.
Actual ExactDisk 1.0 capture in Demo Mode. No reclaim is permitted for the items in this sample view.
Three useful approaches
Which one fits your workflow?
There is no universal winner. The right tool depends on whether you're exploring a whole disk or investigating the generated files left behind by your development environment.
02 / VISUAL EXPLORATION
DaisyDisk
Choose it for a polished general disk map, fast exploration, file previews, and broad local, external, network, and supported cloud storage analysis.
03 / FREE & OPEN SOURCE
PocoDisk
Choose it for a free, MIT-licensed native macOS disk map with sunburst navigation, Quick Look and a collector workflow.

“Not a stated product focus” does not mean a competitor cannot inspect developer folders. Every tool still requires the user to understand what they are selecting. ExactDisk's project attribution and classification are limited to supported detectors, observable signals and folders you authorize; classification is not a guarantee of safety. Comparison based on publicly documented features as of October 2026.

The ExactDisk difference
Projects first. Reclaim only when checks agree.
See what created the space. ExactDisk relates supported toolchains and generated storage to the projects using them, instead of treating every large folder as a cleanup candidate.
Understand the risk. Its classifications explain why an artifact is Safe, Rebuildable, Review, or Never touch—without an AI making deletion decisions.
Keep control. Scanning and planning are read-only. Reclaim requires explicit confirmation and fresh checks; an ambiguous or blocked item stays in place. Successful operations move eligible items to macOS Trash, not permanent deletion.

Find the project. Understand the artifact.
If build outputs, package installs and generated files are spreading across your development projects, ExactDisk helps you understand their provenance and offers a conservative way to reclaim only eligible storage.
