Why does Visual Code create hidden files, and how do I stop it?

Everything that touches Visual Code gets copied and then displayed on the side as a hidden file… but annoying because it’s actually not hidden and stressing my OCD. How do I prevent visual code from making copies of every single file in the first place?

Thank you.

To clarify, I want Visual Code to NOT make any copy. I do not need additional files. I could delete all of them, but to do that every single time I use VS… well… you get it. How do I stop Visual Code from doing this.

Sorry I have to repeat myself, some people do not like answering questions on a platform for people seeking answers.
