NS2 File Operations

I'm a new NS2 User with a iPhone12. If I want to review my files without making changes, do I just keep loading files, (IE the new file just overwrites the current file, and I either save it or not). I've not been able to find a file "CLOSE" function that I'm used to finding in most software

Kinda Confused, but really liking that my phone has new powers..
