A few quick answers.
Does the demo access my computer?
No. The browser demo uses labeled sample data only. Download the Windows application to analyze your actual disks.
Does the license require the internet?
Purchasing happens online. DiskBOX's device-bound lifetime license can be activated and validated offline. There is no subscription or mandatory online renewal.
Which Windows versions is it for?
One EXE selects a payload for Windows 7–11 and Windows Server. Validation across all older Windows and Server versions is still pending. Server Core uses a read-only CLI. The web demo requires a modern browser.
Are files deleted automatically?
No. In the Windows application, cleanup is staged, revalidated and sent to the Recycle Bin only after your approval. System and protected application paths are excluded.
Are games discovered automatically?
Local Steam and Epic Games manifests are discovered automatically. Unknown libraries and external custom mod/save folders can be linked manually. Game size does not mean reclaimable space.
