Your storage should make sense.
macOS can tell you that space is running out. DiskPal helps you understand why. It scans the folder or drive you choose and lays every large item out by size, so the real storage hogs stop hiding behind vague categories.

Follow the terrain to the big stuff.
Every rectangle represents a real file or folder. Bigger regions use more space. Zoom, pan, and drill down one level at a time.

Understand what you found before acting.
See paths, file counts, modified dates, categories, and the largest items inside a folder. Reveal anything in Finder when you’re ready.
03 · Inspect the evidence
Names, paths, sizes, and context—kept together.
Evidence, not guesswork.
DiskPal shows both file size and allocated size, because those numbers can tell different stories. Its category breakdown is paired with names and paths, not just colors, so you can decide with context.
- Ranked “largest inside” lists
- Logical and allocated-size views
- Finder reveal and path copying
- Permission checks for protected folders
04 · Stay local

Five answers · about two minutesWhat is DiskPal?
DiskPal is a native macOS disk space analyzer. It scans a disk or folder, visualizes usage as an interactive treemap, and shows the details behind large files and folders.
Does DiskPal upload my files?
No. DiskPal performs its scanning and analysis locally on your Mac. It does not need to upload filenames, paths, or scan results to explain your storage.
Can DiskPal scan external drives?
Yes. DiskPal can inspect internal and external volumes as well as folders you select.
Why does DiskPal ask for folder access?
macOS protects some locations. You can explicitly select a folder, and protected system areas may require Full Disk Access before DiskPal can include them in a scan.
Is DiskPal free?
Yes. DiskPal is free for compatible Macs. Create a free account when you are ready to download the installer.
