Q:

Git pull -The following untracked working tree files would be overwritten by merge

I am trying to do git pull in master branch and I see this message with a long list of files
The following untracked working tree files would be overwritten by merge:

I really don't care if these files are over written or not, as I need to get the latest form remote. 
I have looked into it and I cannot do git fetch, git add * and git reset HARD
When I do git status, it shows me the list of only untracked files. I don't want to commit these files 

A:

you may delete the untracked files before getting a pull from remote
git clean -f

add the flag n to see a dry run of the files that would be deleted.
git clean -f -n
