On Windows, Notepad++ is probably the second most popular text editor available, just behind Microsoft Notepad.

At the point of writing this article, Notepad++ supports over 50 programming languages. It offers syntax highlighting, code folding, side-by-side document viewing, and a whole bunch of other useful features. Notepad++ features is also extendable using plugins.

I don't normally use it since I mainly interact with Linux, but once I have to get my hands on a Windows machine, Notepad++ is my text editor of choice.

In this article, I will show you how to remove blank lines, with and without whitespace characters, tabs in Notepad++.

  1. TextFX have been removed from Notepad++ 64-bit, why?

    As to why Notepad++ removed TextFX from 64-bit builds: the project has been dead for 9 years, and currently there is no one maintain it. Original source code for version 0.25 (dated 2008) can be fround from https://sourceforge.net/projects/npp-plugins/files/TextFX/. That code can be made to build on modern Visual Studio and it supports Unicode, but 64-bit build is impossible.

  2. What plugin can replace TextFX?

    Currently, some plugins are taking over some areas where TextFX is being used:
    Code alignment, NppConverter, XBrackets Lite, Tidy2
