How do you show a hidden folder (whose name starts with
.) in File Manager a.k.a. Nautilus on Ubuntu? I am somewhat new to Ubuntu and can't seem to find the "view" menu.
Ubuntu 18.04 and newer
The accepted answer is correct for older versions of Ubuntu.
For newer versions, the image displayed below works
In the top right corner of file explorer, there is a menu button displayed as 3 stacked line (hamburger menu), clicking on that will open a modal, on that there is an option Show hidden files
