Real folders and sizes from a freedisk.space scan · tap to replay

Your files stay yours.

Scanning and analysis run on your computer, even across a full disk.

Follow the space.

Go from a block on the map to its folder, its files and why it’s there.

Decide before Trash.

Stage items in Cleanup, read the reason, then confirm the final move.

Every gigabyte
has a name.

The map and its six views, storage categories, Developer Storage, duplicates, history and Cleanup — on Mac and Windows.

What's new Source Build it yourself
Developer Storage

The storage your tools leave behind, explained.

Dependencies, build output and caches are more useful when you know which project made them. freedisk.space connects those folders to their tools and shows what rebuilding them may involve before you decide what to review.

  • See the project, not just the path.

    Group artifacts by project and ecosystem, then see where the space is concentrated.

  • Know the rebuild cost.

    Lockfiles, source activity and project context help distinguish easy rebuilds from dependencies that need extra care.

  • Keep the decision yours.

    Review warnings and tool-specific guidance; staging never removes the folder on its own.

Why freedisk.space

Useful answers beyond “what’s large.”

Storage is more than a list of big files. freedisk.space helps you understand what is shared, what changed, and what moving an item could affect.

Duplicates

More honest savings.

APFS clones can share disk blocks even when files look duplicated. freedisk.space labels shared storage and keeps recovery estimates conservative.

History

See growth over time.

Save a local snapshot and compare it with a later scan to find the folders that actually grew.

Cleanup

Review before Trash.

Files go into a visible Cleanup queue first. You confirm the final move to Trash, with context and warnings still in view.

Storage history

See what changed.

Save a local snapshot, scan again later, and see which folders grew. freedisk.space shows the change next to the folder it belongs to, so you can find the cause before reviewing any files.

  • Compare two saved scans
  • Follow the largest increase
  • Inspect the files behind it
