I want to add an option under Create New to create a file of particular type. For example I use Rnote to create notes,. They have .rnote extension.

Now I create a empty file (image, 3rd option from above) with extension as .rnote , but that file when opened in the application can’t be written to, because it is not a proper .rnote file, it is empty file with that extension.
How do I quickly create a proper file for rnote or any application for example libreoffice?
I am on fedora 43, kde plasma.


Don’t know if this is true for all environments, but you might be able to just create a file in ~/Templates for it to show up in that list.
At least it should, if the file manager follows XDG desktop standards. Btw, you can customize the path in ~/.config/user-dirs.dirs file.
That does it. Thank you. 😀
