What Notepad++ does
Notepad++ is a GPL-licensed Windows text and source editor built on Scintilla. It provides syntax highlighting and folding for supported language definitions, tabbed documents, regular-expression search and replace, multi-editing, column mode, macros, sessions, and a plugin interface. Responsiveness and maximum practical file size depend on the file, encoding, plugins, search operation, available memory, and build; this page does not claim it outperforms another editor.
This record pins Notepad++ 8.9.8 x64, ARM64, and x86 installers plus the x64 portable ZIP from the project's official GitHub release. The release also publishes detached.sig assets, and GitHub exposes reference SHA-256 digests for the versioned files; the release is not marked immutable. The portable ZIP avoids the installer, but it is not a bypass for operating-system policy: the extraction folder must be writable as needed, plugins and settings still persist somewhere, and update behavior should be tested for the intended configuration.
Plugins are separately maintained executable components with their own compatibility, trust, licenses, update paths, and network behavior. Specific plugin examples are not treated as built-in features. The core editor can edit local files offline; plugin installation, online update checks, and network-backed workflows require connectivity. This audit did not run the binaries or validate their detached signatures.
