See what's taking up space on your disk

Disk Space Map shows a folder or a whole drive as a map where every rectangle is a folder or file, sized by how much it holds. Click into any folder, see the largest files, and move what you don't need to the Trash.

Disk Space Map

What it does

  • A map you can click intoA treemap or a sunburst, coloured by kind of file. Click a folder to go in and the breadcrumbs to come back out.
  • The biggest things firstThe largest folders and the 100 largest files, plus a breakdown by type: photos, video, music, documents and more.
  • Clear space safelyMove a file or folder to the Trash from the map. System and app folders, your home folder and a drive's top level can't be moved.

How it works

Disk Space Map in three steps

  1. Choose what to map

    Your home folder, this computer's drive, an external drive, or any folder.

  2. Let it walk the folders

    It counts every file and folder; a large drive takes a minute or two.

  3. Explore and tidy

    Click into the largest areas, show items in Finder or File Explorer, and move what you don't need to the Trash.

Good to know

What it can and can't do

  • Some folders are protected by the system and can't be opened without extra permission; they are listed so you know their space isn't counted.
  • Sizes are file sizes, which can differ a little from the space they take on the disk.
  • Links are not followed, so nothing is counted twice.

Questions

How do I see what is taking up space on my Mac?
Map your home folder or this Mac's drive. The largest rectangles are where the space goes; click into them to find the files.
Can I delete files from the map?
You can move them to the Trash, after a confirmation. Empty the Trash to free the space.
Why doesn't the total match my drive's used space?

Yes. Disk Space Map is free in AMWT Desktop.
