Description
SpaceSniffer is a portable disk space analyzer for Windows that shows drive usage as a treemap. Instead of listing folders in a table, it draws files and directories as nested blocks, so large space consumers become visible immediately and smaller items remain available as you zoom deeper into the layout.
The program is useful when a drive appears full but the cause is not obvious from File Explorer. You can scan a partition or folder, watch the map populate while the scan is still running, filter by file name or size, and move through folders using browser-like navigation without installing anything into Windows or adding normal application entries to the registry.
SpaceSniffer Features
SpaceSniffer focuses on fast investigation. The treemap makes video folders, forgotten archives, virtual machines, backups, and oversized application caches stand out visually, and the zoom controls let you inspect those areas without losing the surrounding drive context. That makes it useful for both quick cleanup and more careful storage audits.
Because it is distributed as a ZIP archive, SpaceSniffer is also easy to keep on a USB maintenance drive. It stores configuration in its own files, supports drag and drop, can export scan data, and offers filtering and tagging tools for users who need to document or revisit what they found during a cleanup session.

SpaceSniffer Review
SpaceSniffer works best when you need a visual answer quickly. After selecting a drive or folder, the largest storage consumers appear as the biggest rectangles, so a bloated download folder or forgotten disk image is much harder to miss than it would be in a traditional folder tree. You can then right-click, open, or delete items from the context of the map.
The interface is compact but more powerful than it first appears. Back, home, and rescan controls help when you have zoomed several levels deep, and filters can separate the files you care about from routine operating-system noise. Advanced users can combine filters and exports, while home users can still reclaim space with only the main scan view.
Care is still required on the Windows system partition. SpaceSniffer can show operating-system files, application data, restore points, and other items that should not be removed casually. The tool makes large files easy to identify, but it does not replace judgment about whether those files are safe to delete.
As a free, clean, portable disk analyzer, SpaceSniffer remains a strong choice for Windows storage cleanup. Its treemap view is immediate, the scan behavior is fast enough for everyday troubleshooting, and the export features give administrators a useful way to preserve findings after a storage review.
