How to remove untracked files and directories?

git clean -f -d

To remove untracked files and directories from the working directory use git clean -f -d.

Since git clean removes files it's recommended to start with a dry-run using parameter -n. A dry-run will show what is going to be removed without actually removing them.

The -f parameter tells git to remove the files when git clean is used. The usage of parameter -f is required unless clean.requireForce is configured to false.

The -d parameter tells git to clean files recursively and remove directories as well.
