Hello, how are you?
My name is Paloma B., I am very happy to be able to try to help you in the best possible way.
This is an open community, whenever you need you can share the problem so that possible repairs are suggested.
I recommend downloading the TreeSize tool and evaluating which folders are consuming a lot of space and delete it if it's not system file folders.
With this tool it will be easier to identify which folders are taking up a lot of space and if you really copied them twice.
