Does it matter how many folders the file will be hidden in?

Question

PHP

I saw a warning from Google that it is necessary to minimize the nesting of files.
Those. reduce different folders in folders for files.
Is it so important for speed and work if everything is stored not in the first folder, but let's say there is another folder in the folder in which there is another one, and there are already files?

Answer 1

You misunderstood google. He meant to minimize "needle in the egg, egg in the hare, hare in the duck, duck in shock", that is, for example, when you have an html document, it contains a script that loads CSS, in CSS a link to a file with a font (especially cool when all this is on different domains that need to be resolved and installed HTTPS handshakes with each one in turn).
