How do I restore the Templates folder in Ubuntu 18.04?
Solution 1:
By default, this folder is empty.
It is declared for Gnome Shell in this file
~/.config/user-dirs.dirs
Where should stand the line
XDG_TEMPLATES_DIR="$HOME/Templates"
Of course, the Template Folder name depends on your locale and language
If the line has been removed because off the deleted folder, you will just have to create a new one and add the line.
