Notepad2 – Lightweight Text Editor

Overview

Notepad2 is a fast, lightweight, and feature-rich text editor designed as a superior replacement for Windows Notepad. Created by Florian Balmer using the powerful Scintilla editing component, this open-source editor combines the simplicity and instant startup time of Notepad with advanced features like syntax highlighting, code folding, and regular expression search that developers and power users need.

Despite its remarkably small footprint of under 1MB, Notepad2 delivers impressive functionality suitable for everything from quick text edits to programming tasks. The editor supports syntax highlighting for over 40 programming and markup languages, includes auto-completion features, and provides a modern editing experience while maintaining the lightning-fast startup that made the original Notepad popular among Windows users.
