DiskLensDashboard
The big picture first: how much space is free, how much is used, and where it goes by category and file type — before you dive into any detail.
Everything in DiskLens.
One fast scan, six ways to understand it, and a design that respects your privacy.
Treemap
Every file becomes a tile sized by how much space it takes. Color the map by file type to spot what kind of data dominates, or switch to a size heatmap to find the single biggest offenders.
Sunburst
A ring chart that mirrors your folder tree. Click any segment to drill in and follow space down through the hierarchy, toggle labels, and export the dial as a PNG.
Details
When you want the numbers, the Details table sorts every folder and file by size, count or date — and exports the whole report to CSV or a shareable HTML file.
Search
Filter the entire scan by name as you type. Switch on regular expressions for precise matches, and choose whether folders count as results too.
Duplicates
DiskLens compares files by their actual content, so it finds true duplicates even when the names differ — then leaves the cleanup decision to you.
Under the hood
Fast, native, and considerate.
Built for speed
DiskLens reads each folder with a single bulk system call instead of stat-ing files one by one. Scans finish quickly and stay easy on the CPU, even across millions of files.
Stays where you point it
By default a scan stays on the volume you chose and skips mounted network shares and external drives — so a single mapped share can't quietly inflate the totals. One toggle includes them when you do want them.
Favorites & Recents
The sidebar remembers the folders you scan most and lets you pin the ones you return to, so your next scan is one click away.
Private by design
Sandboxed, with no network access at all. DiskLens reads only the folders you grant it, collects nothing, and keeps every byte on your Mac.
