iCloud - Deleting a file in iCloud, deletes the file in my Mac too
I don't know what I have done. Finder started to copy all my documents to iCloud and now when I try to delete a file in iCloud, it is also deleted in my Mac.
How is this sync stopped? I want to keep my documents in my Mac. I don't want to touch nothing because I have just read that someone tried to unsync the iCloud thing, and all his documents were lost.
Help please, I fear for my files.
MacBook Pro 13″, macOS 11.3
