What is notepad.exe?

notepad.exe is the executable for Windows Notepad, a lightweight plain-text editor built into Windows. It opens quickly, edits simple text files, and saves in UTF-8/ASCII formats. Notepad’s minimal UI and tiny footprint make it ideal for quick notes, logs, and basic scripting tasks.

Notepad runs as a simple, low-resource editor with a small memory footprint and no plugins. It typically uses a single process per open window, handles UTF-16/UTF-8 text, and relies on the Windows text subsystem for file I/O and encoding.
