I have installed a closed source office suite called Freeoffice. Generally, I use Libreoffice for all my work and need Freeoffice only as a backup to check if there are any inconsistencies in formatting when i need to edit collaborative docx documents and send them to MSOffice using clients.
My problem is, that each time I update Freeoffice it sets itself as the default application for all office related document formats. I then have to manually change each of them, which I often forget as there is a ton of related Mime types.
Is there a way to find all MimeTypes that are associated with Freeoffice and decrease its rank, so that it is no longer the default?
PS: I use Kubuntu 19.04 and am in search of a KDE solution.
