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
Ubuntu 20.04/ 21.04/ 21.10
Using the Nautilus option
Show hidden files will only resolve the issue temporarily, but there are ways to set this as the default option.
There is a nice one-liner to do this:
gsettings set org.gnome.nautilus.preferences show-hidden-files true
The settings will take effect immediately (even for currently running instances).
As posted above you may install
sudo apt install dconf-editor
Then search for
show-hidden and activate the option
As you can see in the following screenshot the "same" option also exists for other applications such as the Gtk FileChooser, so make sure you activate the setting where you need it.
dconf-editor will also show you the key to use for each setting in case you want to set it using
gsettings as outlined in the first section of this post.
