Regrettably I uploaded a folder named 3d Modeller to GitHub. I want to change the name to Modeller as if I upload separate files they get stored in an extra 3d%20Modeller/, whereas bulk uploads get stored in 3d Modeller/ ... hence the regrets! Answers I found here are beyond me. Anyone know a solution for a simpleton?
Edit:
Actually I was looking for a gui solution - hence for simpleton - that might have arrived within the last year or two. If there's a gui then it seems probable that it will become as comprehensive as its old time counterpart. Seems not so, so have to accept as duplicate.
