I am a designer and use a lot of different fonts. There are some pre installed fonts on the laptop and some options in software. I have more .ttf fonts and can I just place these in a folder? Or do I have to make a new folder and will it see them directly? There are many places where I find .ttf fonts.
As Kieran said, to move fonts there, you need to act as root by using sudo from the terminal. I think you can create a hidden directory under your home directory called .fonts (the . in front will automatically make it hidden) and then put font files in there. I haven’t tried this, but some documentation I’ve seen suggests that is another location that gets scanned for fonts. You wouldn’t need sudo for this and could even do it from the graphical file manager.
Alternatively, it seems like you might actually just be able to double-click the .ttf file to open it with GNOME Font Viewer, which then provides an option to install it. Again, haven’t tried that, but saw some documentation which suggested it.
(Forum software won’t allow a file: link, understandably.)
says go look in (among other places) /etc/fonts/fonts.conf for the config
and that says (in part)

I don’t know how definite or how soon the “will be removed in the future” is.
