How to rollback unstaged changes?

Question

git

There are several files under the git.
1. I make changes to one of them (for example, I add text)
2. I create another file
3. The git add command. I don't
. Now I would like to roll back the changes. What command should I use for this?
I must say right away that it git reset --hardwill roll back the changes in the file, but will NOT delete the created file. This solution does not suit me
. The command git clean -d -x -fwill delete the created file, but will not roll back the changes in the previously existing file
