Remove default extension in Style Configurator

[NotepadPP_User]

I’d like to open *.S files as if they are Assembly files (same as *.asm).

I can add “S” to “Assembly” in the style configuration user defined extensions. But, I cannot remove the current mapping for “S” which is assigned to the “R” language.

Therefore, “S” files will always be opened as if they are “R” language files.

How do I remove “S” file types from the “R” language parser?

Didn’t try it by myself but my guess is:
Settings --> Preferences --> Language Menu
Move ‘R’ to disabled.

You have to edit the file

C:\Users\<UserName>\AppData\Roaming\Notepad++\langs.xml

Search the following Language node:

<Language name="r" ext="r s splus" commentLine="#">

You have to remove the s in the value of the attribute ext.

Thanks, this worked. maybe the GUI setting could allow this in the future.
