What files to delete in Galaxy s5?

[AC Question]

I'm not a computer geek so I know nothing about codes. I've been deleting the "Android" folder to clear up some space. I don't really know what's in it, but I've been doing it for a while now and the folders come back anyway after I delete them.

Questions I need answers to:
Is this safe? Can it damage my system? How will I know if my system is broken and how can I fix it? What files can I delete? Thanks!

Welcome.
Unless you know what you are doing, do not delete anything.
