How to restore preferences, ect...

I have to format my notebook.
Once I've done it, when I'll reinstall Da Vinci Resolve, I'd like to find again all my preferences, new fonts, etc...
I mean: I've already exported all my projects, but I even have got my Da Vinci completely customized (keybord, preferences, fonts, etc...) and I' don't know how to restore all of them once I reinstall Da Vinci on my notebook

Keyboard preferences are exportable/importable -- assuming it's not to late for you to export from a working system. But these and other non-project preferences are also stored in the database(s). If the databases gone, so are the system-wide preferences.
