Duplicated folders in github

Question

I have an app that is been tracked using git and the repository is hoted on github.

In my local computer the folders and files are these:

Answer 1

They arent duplicates: TulpepWebsite and TulpepWebSite (note the capital S).

You probably renamed the folder and git may have not removed the now non-existent folder... check this with git status, and then manually remove the folder from git by running git rm TulpepWebsite/
