EmEditor Professional, a lightweight text editor for Windows, supports Unicode (UTF-16, UTF-8, and UTF-7), as well as many international encodings.


EmEditor allows you to open huge files (>248GB) quickly and easily, and is optimized for speed and reliability. The Large File Controller maximizes productivity by opening sections of enormous files for faster editing.


In a speed comparison test, EmEditor performed better than 10 other text editors in four different categories, including launch time and time to open large files.


Features include JavaScript or VBScript macros, plug-ins, syntax highlighting (including embedded scripts in HTML, ASP, and PHP files), drag-and-drop, CSV and TSV mode, Narrowing, Brackets/Quotation Mark Auto-Complete, and much more. The text editor supports not only JavaScript and VBScript for the text editing macros, but also PerlScript, PHPScript, Python, Ruby, and many other ActiveScript languages as long as the script engines you want to use are installed on your system. Binary (ASCII View) and Binary (Hexadecimal View) are included in the available encodings.


The text editor can record and play keystrokes and mouse operation against other applications, and includes plug-ins such as Projects and Word Complete, lots of objects for macros, the Macros Toolbar, and portability options (such as USB drive setup), virtual space mode, wrap indent, smooth scroll, and crash auto-recovery.


Version 10 includes a Compare Documents feature that allows you compare two documents side by side with Synchronized Scrolling and highlighted differences. Vertical Selection Editing allows you to replace multiple lines quickly without using regular expressions. Other new features in v10 include Spell Checking, ASCII View side by side with Binary (Hexadecimal View), and numerous improvements to plug-ins and other features.


EmEditor is compatible with Windows 7/Vista/XP/Server 2008/Server 2003/2000.
