Welcome,
Probably most of persons working with Git version control had a situation when they accidentally removed commit or reset files which should be added into changeset or somehow broken rebase process. Now the question is - how to revert move?
You can always revert your previous files state using reflog (if you added them to the commit). Reflog stores all operations executed on all of git branches existing in your repository.
Example reflog could look like the following:
$ git reflog
206e6dd HEAD@{0}: rebase finished: returning to refs/heads/dd
