Current official release: 1.1.1. Windows 10 2004+ or Windows 11 (x64).
Osenpa Disk Analyzer is a free, closed-source Windows app for investigating storage use. Scan one drive or connected drives, inspect file and folder sizes, and filter by category or name. Supported NTFS volumes can use MFT scanning with folder-traversal fallback. Review access warnings and inspect item locations before removing anything. Size and age alone do not mean a file is safe to delete. Name results display up to 2,000 matches. Scanning stays local; launch checks use the network, and optional online search can share a selected path.
Current downloads are available from the Official Download link: https://osenpa.com/osenpa-disk-analyzer. Earlier EXE files have been removed from this SourceForge page. License terms accompanying previously distributed copies are unchanged.
