How to revert uncommitted changes including files and folders?

Question

Is there a git command to revert all uncommitted changes in a working tree and index and to also remove newly created files and folders?

Answer 1

git clean -fd

didn't help, new files remained. What I did is totally deleting all the working tree and then

git reset --hard

See "How do I clear my local working directory in git?" for advice to add the -x option to clean:

git clean -fdx

Note -x flag will remove all files ignored by Git so be careful (see discussion in the answer I refer to).
