Q:

Delete all the local files and download a fresh copy from git

I understand it is possible to delete everything locally and just start fresh but I wonder if there is an easier way when you do not require to keep anything done locally using git commands.
for example if I added bunch of files locally that I would like to remove and just download the latest master copy.

Please note: Reading the other questions (there are many; I read them before posting), git help & blog posts I wasn't sure if it's going to reset my repository or not which is why I posted this question; I imagine someone with
  the same exact issue might want to validate and that's what I have done through comments. and that is why I don't think its a duplicate although it might have the same response.

A:

To remove the git commit which you have added locally do:
git reset --hard HEAD^

To remove the remove the uncommitted files, do:
git clean -fd

check out other git Clean options here:
https://git-scm.com/docs/git-clean
and then do 
git fetch
git rebase origin/master

or 
   git pull
