Notepad++ has been a very popular open source code editor and text editor for a long time. Licensed under the GPL and available for Windows, many people use it as a replacement for Windows Notepad, and as an editor to write blog posts in, where it won't introduce the same formatting problems that some word processors do (which can throw off a blog engine). In SourceForge's last Community Choice Awards, it was named Best Tool or Utility for Developers. Now, the folks at PortableApps have announced a handy new portable version of it.
The portable version of Notepad++ is only 10MB in size, so you can easily run it from a USB thumb drive at any computer, anytime. Among the features are:
 * Syntax Highlighting and Syntax Folding (C, C++, HTML, ASP, Java,    Pascal, CSS and more)
 * User Defined Syntax Highlighting
 * Auto-completion
 * Multi-Document
 * Regular Expression Search/Replace supported
 * Full Drag ‘N' Drop supported
 * Zoom in and zoom out
 * Multi-Language environment supported
 * Brace and Indent guideline Highlighting
 * Macro recording and playback
