Dashboard
An at-a-glance overview of the volume, with space broken down by category and file type.
See where your storage went.
DiskLens scans any folder — or your whole disk — in seconds and turns it into clear, interactive visualizations, so the biggest space hogs jump right out.
On the Mac App Store · Requires macOS 26 or later · Sandboxed and private.
See it in motion
Watch a real scan.
A quick tour: explore a scan as a treemap, find duplicates, search — then make it yours.
Six ways to look
One scan, every angle.
Point DiskLens at a folder and explore the result however you think best.
Treemap
Every file as a sized tile, colored by type or by a size heatmap. The biggest items are impossible to miss.
Sunburst
An interactive ring chart you can drill into to follow space down the tree — and export as an image.
Details
A sortable table of folders and files, with one-click export to CSV or HTML for reports.
Search
Find files by name across the whole scan, with regular-expression support and optional folder matching.
Duplicates
Find identical files by content — not just by name — so you can reclaim the space they waste.
See it in action
Click through the interface.
Switch between the views just like in the app — right here in your browser.
Dashboard — free space, totals, and a breakdown by category and file type.
Click a view in the window's sidebar or the tabs, and flip light / dark.
Make it yours
Wallpapers, a tunable lens, light or dark.
Set the appearance, sidebar sections, wallpaper, start-screen lens, and duplicate exclusions.
General — appearance (Light / Dark / System) and launch behavior.
Private by design
Your disk is your business.
DiskLens runs in the App Sandbox and only ever reads the folders you explicitly choose. It collects no data, contains no ads or trackers, and nothing ever leaves your Mac. By default it stays on your selected volume and won't wander into mounted network shares or external drives unless you ask it to.
