I am using PaleMoon, a Firefox derivative. I have a unique filetype that I want to open in a custom application from the browser.
I need the file extension linked to the application in mimetypes.RDF.
I already have known file types registered in mimetypes.rdf, but I want to add a unique extension that we only use internally.
Please: no ChatGPT responses.
Don't apply if you have a brother who has a friend who saw someone do this. Only apply if you seriously know how this is done. And, no, I don't care if you have a large pool of certified programmers who could probably figure this out.
