EmEditor Professional is a lightweight, yet extensible, text editor for Windows, which supports Unicode (allowing for multi-language support). EmEditor allows you to quickly and easily open or edit huge files (up to 248GB or 2.1 billion lines), using a large file controller, and is optimized for speed and reliability. Compatible with Windows 7 and older Windows systems.
EmEditor Professional can record and play keystrokes and mouse operations against other applications and includes plug-ins such as Projects, Snippets, HTMLBar, FindBar, Outline, and Word Complete. The program also includes portability options (such as USB drive setup) through an Import/Export wizard, as well as virtual space mode, wrap indent, tabbed window design, vertical selection editing (to allow the simultaneous editing of text in multiple lines), binary editing, smooth scroll, a theme feature for color settings, and crash auto-recovery.
