Storage Insights

Disk Usage Visualizer

See exactly where your storage is going. Drill into folder sizes, spot file-type hotspots, and decide what deserves a duplicate or junk pass next.

Key Features

What each module does.

Native Windows app. Hashing, indexing, and batch apply run on your machine.

Visual

Navigate a hierarchical view of your directories. Drill down into the deepest, largest folders and see live scan progress.

Insights

Charts highlight which extensions consume the most space (videos, disk images, archives) so you know where to focus cleanup.

Actionable

Found a massive cache folder? Act on it from the same toolkit with preview, undo, and Recycle Bin defaults.

See the Big Picture

Windows Explorer hides folder sizes until you drill into each tree. Disk Usage ranks directories first so you know where to run dedup or junk scans.

Discover massive application caches hiding in AppData or project export folders.

Highlight videos or disk images to quickly find the largest media files.

Your file structure is never uploaded. The entire disk map is generated and stored locally on your device.
