You can use tree to print the directory tree in terminal. Install tree from terminal,

sudo apt-get install tree

To see the directory tree, use

tree /path/to/folder

Or navigate to a directory and just use

tree

It has some advanced options too. You can see owner's username, groupname, date of last modification of a file/folder and so on using tree. It supports directory colors of ls so you can see colourized outputs.

See man tree for more.
