WinShun

Project Overview

WinShun is a free, open-source quick search launcher for Windows: press Ctrl twice for a search box that returns results as you type, finding files by name or pinyin initials and searching text inside Word, Excel and PDF documents.

It builds its index straight from the NTFS Master File Table, indexing three million files in seconds with real-time updates for renames, additions and deletions. No Everything required, no account, and no data ever uploaded.

Notes

• NTFS indexing: indexes rely on the NTFS MFT, non-NTFS partitions and network locations have limited support
• NAS inclusion: SMB shared folders can join the index and stay searchable when the server is offline
• Isolated document reading: full-text search reads documents in a restricted helper process, keeping the main app unaffected
