I am starting to build a website from scratch using python, django, and bootstrap. I have noticed that many times js, css, img. and fonts are stored in a folder vendor, such as:

/static/js/vendor/bootstrap/bootstrap.min.js

/static/css/vendor/bootstrap/bootstrap.min.css

or something similar.

What is the benefit of this folder structure over something like:

/static/bootstrap/js/bootstrap.min.js

/static/bootstrap/css/bootstrap.min.css

In the first example, when using the vendor folder as I have often seen, I would have to download bootstrap and unpack the downloaded folder into the js and css vendor sub-directories. In the second example, I can download bootstrap and drop the downloaded folder into /static without having to unpack anything.
