How can I tell Notepad++ to always use a particular language with a particular file extension

Question

I've associated .xul with Notepad++ so if I double-click on a .xul file, it will open in Notepad++. But Notepad++ doesn't know that XUL is just a particular type of XML, so I then have to manually click on "Language > XML" to get XML syntax highlighting. Is there a way that I can tell it: "every time you open a file with the extension .xul, automatically switch to the XML language"?

Answer 1

All you have to do is tell Notepad++ that "xul" files are actually "XML" files.

1. Go to Settings > Style Configuator
2. Under Language, scroll down and highlight XML
3. At the bottom, under "User ext." type in "xul"
4. Hit "Save & Close"
5. Open your file and it should now highlight properly.

I should note that this has already been asked. Take a few moments to look around before you ask a question.
