Notepad++ (text editor)

notepad-plus-plus.org

The single greatest text editor ever made, in my humble opinion. Notepad++ is aptly named for having all of the features of notepad, plus more, plus more than that. It has integrated code highlighting for just about every language ever made, collapsible code blocks, smart formatting, encoding selection, macros and support for custom plugins. It has an amazing feature set, lots of customizations and is extremely fast and stable.

The only features I’ve ever missed from Notepad++ is support for #region tags and the ability to open gigabyte files.
