01 · Visual, local-first

See the whole disk, then go straight to the file

FileTree Pro scans a folder or drive and lays it out as a space map, a treemap and a sortable list. It surfaces large files, duplicates and cleanup candidates, but you always decide what moves.

01

Scan

Choose a folder or drive to analyze.

02

Verify

Read the map, the list and the hash checks.

03

Clean up

Move only approved items to the trash.

Look from the whole drive down to one file

The radial map, treemap and list all read from the same scan. Go from the whole drive down to a single folder or file.

Cleanup

Only approved items go to the trash

Duplicates are confirmed by SHA-256 content hashes, and every suggestion shows its evidence and confidence level. There is no permanent delete, and each item is rechecked right before it moves.

When the disk fills up

Finding out why a drive suddenly filled up

02

Developers with growing piles of regenerable data such as node_modules and caches

03

Copies of the same videos and archives spread across folders

04 · Privacy & safety

Your files stay on your device.

Scanned paths, file names, metadata and hashes never leave your computer. There is no account, advertising, analytics or telemetry, and reports are created only when you choose to export them.

Processed on your computer

Scanned paths, file names, metadata and hashes stay on your device. There is no account, telemetry or cloud upload, and cleanup uses the system trash instead of permanent deletion.

Can FileTree Pro permanently delete files?+

No. FileTree Pro has no permanent-delete command. Approved items move to the Windows Recycle Bin or the macOS Trash, and each one is rechecked right before it moves.

Does it need administrator rights?+

On Windows it runs with standard permissions and never elevates on its own. When scanning a local NTFS drive root, you can choose to restart as administrator for a faster, read-only analysis. On Mac it runs in the App Sandbox and scans only locations you authorize.

Why can displayed size differ from reclaimable space?+

Cloud placeholders, compression, hard links and APFS clones can all cause a gap. Locations that cannot be read are reported as partial results instead of being silently skipped.

What are the system requirements?+

Windows 10 version 2004 or later (x64), or macOS 12 or later on Apple silicon and Intel-based Macs.
