Open Source Visual Basic .NET Disk Space Analyzers

SpaceSharp is a free, open-source disk space analyzer for Windows 10 and 11, inspired by SpaceMonger. It scans an entire drive or a selected folder and draws it as an interactive, zoomable treemap: every folder is a frame, every file a box sized by the space it uses, so the big things stand out at a glance. NTFS drives are read straight from the file table, so a million files take seconds. Features include a filter drawer with file types, size, age and presets, a panel showing space by type, places that are safe to clear and when files last changed, saved scans with a view of what changed since last time, fifteen palettes and adjustable shading with a live preview, dark and light themes with five looks each, size-on-disk measurement, hard-link detection, CSV export and a command line. Files can be opened in Explorer or sent to the Recycle Bin from the map. Portable and installable builds for 64-bit and 32-bit Windows. MIT License, actively developed on GitHub.
