I also had this problem for some time: turns out C/C++ extension automatically created them for every directory that you open. I uninstalled it and it stopped.

Those .vscode files are where it stores the per-project settings that the poster you replied to said they really liked.

It shouldn't create .vscode folders unless it's storing project-specific launch configs, settings, tasks, or extensions in there.

I have not had this happen except if you pick project settings instead of user settings, i noticed it generated some files.

Outside of that, i havent had this happen. However, if it is simply annoying in your editor you can put them in .gitignore and either tell vscode to not list anything in the .gitignored list, or explicitly ignore files and folders by default.
