SpaceSniffer-2026 shows you which files and folders take up space on your hard drive. It displays data as a visual map of blocks. Each block represents a folder or file. Large files appear as large blocks. This system helps you see exactly where your storage space goes. You find large, unnecessary items quickly and remove them to free up space.
This software works on Windows 10 and Windows 11. It requires no complex setup. Ensure you have at least 50 megabytes of free space on your drive before you begin. You need standard user permissions to run the application.

This download includes the main program. You do not need to install extra components or drivers.

The application begins to scan the drive immediately. You see blocks fill the window while the program works.
The interface shows your disk as a treemap. Each rectangle represents a single folder or file.
If you want to move back, click the arrow icon at the top of the window. You can adjust the view settings in the toolbar to change how the application renders the blocks.
The tool helps you find space, but it does not delete files automatically. You maintain full control over your data.
Be careful when you delete files. Focus on personal files like videos, photos, or documents. Do not delete files inside the Windows folder or the Program Files folder unless you know exactly what they do. Deleting system files can prevent your computer from working.
Does this software store my data? No. The application scans your drive locally. It sends no data to the internet and stores no information on your hardware.
How do I stop a scan? Click the Stop button in the toolbar at any time. The scan finishes instantly.
Can I scan external drives? Yes. Plug in your USB drive or external hard drive. The application detects the drive and allows you to select it during the startup process.
Why does a block appear dark? Darker colors often represent folders with many smaller files. Bright colors represent larger single files.
Does the software slow my computer? The tool uses a small amount of memory. It runs smoothly on most standard hardware. If you have a very large drive with millions of files, the scan takes more time to complete.
