Bridge Storage

See what fills a folder.

Choose one folder on your Mac. Bridge Storage measures it and shows which folders and files take up its space, on a clear map with a matching list. Your files stay exactly as they are.

Free. Requires macOS 14.0 or later and a Mac with Apple M1 chip or later.

The Bridge Storage window showing a sample folder, Demo Library, as a two-level ring map beside a list of its folders: Videos 27.3 MB, Photos 12.6 MB, Music 6.3 MB and Archives 5.2 MB. The report is marked Complete with gaps.
A ring map and a matching list of what fills the chosen folder.

How it works

  1. 01

    Choose a folder

    Pick one local folder with the Mac’s own folder picker, then press Scan. Choosing a folder does not start a scan on its own.

  2. 02

    See what fills it

    A two-level ring map and a matching list show the largest folders and files. Switch between File size and Size on disk, and open any subfolder.

  3. 03

    Decide in Finder

    When you are ready to act, reveal an item in Finder and decide there yourself. Bridge Storage only shows; it never deletes, moves or cleans files.

Inside the app

  • Bridge Storage after opening the Videos subfolder: a ring map and a list with Short film.mov at 18.9 MB and Tutorial.mp4 at 8.4 MB.
    Open a subfolder to see what is inside it.
  • The Largest Files list in Bridge Storage, ranked by size on disk, starting with Short film.mov at 18.9 MB and Travel collection.jpg at 8.4 MB, each with Show in Folder and Reveal buttons.
    Largest Files ranks the biggest measured files.
  • The Gaps tab in Bridge Storage: one unreadable demo folder was not measured, so its size is unknown and left out of every total.
    Gaps lists what could not be measured, instead of guessing.

Honest limits

  • One chosen local folder

    It measures one folder at a time. It refuses the whole disk, volume roots, your entire home folder, network volumes and cloud storage locations.

  • Read-only metadata

    It reads names, sizes and other file-system metadata. It never opens the contents of your files.

  • No deleting or cleaning

    It never deletes, moves or changes your files. Anything you decide to do, you do yourself in Finder.

  • Measurements, not promises

    Shared APFS data, snapshots and changing files mean the numbers are not a promise of how much space you could free.

  • Gaps, not guesses

    Items it cannot read are listed as gaps and left out of every total, so an incomplete report says that it is incomplete.

  • Nothing leaves your Mac

    No account, advertising, analytics or network access. Scan results stay in memory and are cleared when you quit the app.
