I've been trying to change the icon for the filetype *.eml (message/rfc822) within PcManFm (file manager of LXDE) but after severall hours and many lines read and tried, I still cannot find a working solution, neither for PcManFm nor for Nautilus.
I have a 48x48 png file called thunderbird.png which I would like to make the image of the *.eml files
I've tried with:
xdg-icon-resource install --context mimetypes --mode user --size 48 ./thunderbird.png message-rfc822
changed the default icon for the message/rfc822, but it did not changed anything nor in PcManFm nor in Nautilus
and this other solution for Gnome/nautilus
didn't worked also...
Does anyone have a clue/idea of how to solve this?
I'm trying to show a person that everything he does with windows can be done with linux, and he works a lot with email_files.eml that in windows show up with the thunderbird icon...
