In summary, Notepad++ is simply Microsoft Notepad, but on steroid. The editor makes it easy to inspect files at all stages on embedded software projects, from HEX to C++ source. You can work on several documents at the same time, thanks to its multi-tab editing feature. It’s an excellent sidekick for coding projects. It is written in C++ and uses Win32 and STL, which ensures smaller program size and higher execution speed. Notepad++ is more than an editor: it’s a Notepad replacement that supports many different programming languages. Sometimes hangs when dealing with large amount of data.
