Exclude folder from Pycharms duplicate check

Question

Q: How do I exclude a folder from pycharm's duplicate check?

Minimal Example:

Say my pycharm project folder structure looks like this:

project/main.py
project/.backup/main_copy.py

How do I tell pycharm not to warn me that main.py and main_copy.py contain duplicate code?

Answer 1

Try to mark .backup as excluded via right-click on it -> Mark Directory as.
