Frequently asked questions

Everything you need to know about DiskPilot.

Is DiskPilot really free?

Yes, DiskPilot is 100% free and open source under the MIT license. There are no hidden costs, subscriptions, or premium tiers. You get every feature at no charge.

Which operating systems does DiskPilot support?

DiskPilot runs on macOS 11 (Big Sur) and later, Windows 10 and later, and most Linux distributions. Download the DMG for Mac, EXE installer for Windows, or AppImage/deb for Linux.

How is DiskPilot different from built-in storage tools?

Unlike Finder or Windows Explorer, DiskPilot gives you a full folder tree with size bars, interactive treemap/bar/pie chart visualizations, multi-selection, and the ability to delete files directly — all in one fast interface.

Does DiskPilot collect my data?

No. DiskPilot scans your disk locally on your machine. It does not upload file names, sizes, or any personal data to external servers. Your files stay private.

Can I scan external drives and USB devices?

Yes. You can scan any mounted drive or folder — internal disks, external hard drives, USB sticks, network shares, or any path you can access from your file system.

Why does the reported size differ from Finder or Windows?

DiskPilot reports actual disk usage (allocated blocks), not logical file size. This gives you the same numbers as the "du" command and matches what your OS reports for total disk usage. Hardlink deduplication prevents double-counting shared files.
