EmEditor is a fast, lightweight, yet extendable, easy-to-use text editor for Windows. EmEditor Professional is capable of opening very large files — up to 248 GB or 2.1 billion lines — with only a little memory, leaving you free to work as large or small as you please. EmEditor features include multiple selection editing, multiple file encoding conversions, quick launch, matching Tag highlight, improved bookmarks, improved markers, messaging, HTML/XML character references, batch replace, compare and synchronize scrolling, ASCII View side by side with binary (Hexadecimal View), brackets/quotation mark auto-complete, CSV,TSV, Wildcard Support and more!
EmEditor is also available as FREE software. You can use it as Notepad-replacement with enhanced features like syntax-colored highlighting, find and replace function, Unicode support, and printing capabilities. However, this free version does not include many features that EmEditor Professional offers, such as very large file support, plug-ins, macros, vertical selection editing, etc. Starting with v13, EmEditor Free and EmEditor Professional will use the same binary program. Running a single command switches Professional to Free, and vice versa. However, the Free version is available only for personal use.
