Why are there so many inexplicable changes in git?

Question

I don’t know how it ended up like this

Answer 1

This has nothing to do with Git. The problem is that you should not create a Git repository in the User/your_name folder, but create a new folder. Many software will store configurations in the AppData hidden folder in this directory, and the system will also store the HKCU registry, etc. in this folder.

Answer 2

Even so, you can also use .gitignore to ignore those files

Of course, the final analysis is that you should not create the Git repository in the user folder
