How to edit files using blueprint?

Hello!
I’d want to know how to edit a .ini file using blueprints. I’m creating save games for my project now. And I want game to save coordinats of player into .ini file when I click F5. I know how to read coordinats but I don’t know how to save them
(I only know how to print them on screen).

You can use a SaveGame, but I don’t think you can manually read it. Savegames allow you to save and read to files.
