Remove untracked files from the working tree

Step 1 is to show what will be deleted by using the -n option:

git clean -n

//Clean Step - beware: this will delete files:

git clean -f

//To remove directories, run git clean -f -d or git clean -fd
//To remove ignored files, run git clean -f -X or git clean -fX
//To remove ignored and non-ignored files, run git clean -f -x or git clean -fx
