I have downloaded app, does not require installing just start from folder, setup .desktop
file. All works fine. Now I want to associate the file type in Gnome, so I can double-click on a file and it will be opened in that app.
I manage to set up that too, using ~/.config/mimeapps
file. Also, setup icon for that file type. Works great. Where I have problem is that mime file type for this file is application/octet-stream
and this associate many other octet-stream files (basically every unknown file type) to be opened with this app.
Is it possible to somehow narrow this, so a specific file extension is affected? Is it possible?
I am on Ubuntu 20.10 Gnome.
/etc/mime.types
file and reboot.
