SpaceSharp is a free, open-source disk space analyzer for Windows 10 and 11, inspired by SpaceMonger.
It scans a drive or a folder and draws it as a 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.
Insights shows space by type, places that are safe to clear, game libraries, developer leftovers and old downloads. A duplicate finder compares file contents, and an empty folder list skips anything a program needs. Every scan is saved and compared with the last, so you see what grew. A plain-words filter, 24 palettes, dark and light themes and 18 languages round it out.
Everything goes to the Recycle Bin, except folders too deep for Explorer, which it can remove for good. Portable and installable builds for 64-bit and 32-bit Windows, code-signed. MIT License, actively developed on GitHub.
