EmEditor Text Editor is a lightweight, yet extendable, easy-to-use text editor for Windows. EmEditor is very customizable, and it supports Unicode and powerful macros. EmEditor now supports very large files - up to 248 GB or 2.1 billion lines! EmEditor is certified for Windows Vista! The new version optimizes the speed to open a huge file, so it can open a huge file much more quickly than previous versions. The new multithreaded design allows you to view documents during the opening of a file. The Project plug-in now automatically displays the symbol list in another custom bar. The plug-in uses Ctags to create tags, and reads the tags to display the symbol list. All you need to do is to add your files to a project! The new version also optimizes for Find and Replace speed (2 - 8 times faster!), and supports RHTML files (used in Ruby on Rails)!
