Create feature branch for files already pushed to master branch for pull request

Question

I have a master branch with following structure

master (branch)
folderA
folderB
folderC

I want to shift folderC to a feature branch so I can create a merge request to master branch.

It should be like this

master (branch)
folderA
folderB

newFeatureBranch1 
folderC

I have pushed my code to an online repository what is the best way to do this?

Answer 1

From master:

git rm --cached folderC
git commit -m "Remove folderC"
git push origin master

then from the feature branch:

git add folderC
git commit -m "Add folderC"
git push origin featurebranch
