hello sir, very very happy with the lessons. I am a novice programmer and try to understand everything. I have followed and completed the school course 201 lessons and started to understand a bit about the structure of the folders and the files. Only now you no longer use that same structure and I don't really understand what is right or wrong. my question is why different directories and names are now used for the files. Everything else is so clear and all the puzzle pieces always fit. my big compliments. I'm going to follow everything you've made so I can learn more and more.
thank you Han
Merry Christmas and a Happy New Year
