Hi Almarma 😄
You really need to learn how your Mac works- it really helps, and it's not difficult either. If you search for stuff using Spotlight, you will get shown the pathways to directories/ files at the bottom of the window, where you will find what you need to throw away. I would also recommend that you Google "EasyFind", which is a brilliant search utility for Mac, and use that too 😄
I hope that helps 😄
