How can I access an external file within the same folder as the built .exe?

So I plan on building my game (which will run on Windows, Mac, and Linux) and then putting both the data folder and the exe folder into a new folder, which can be called “Game”. But if I add a file in after, called “saves”, how can I save my data to this folder without using the whole file path?

PlayerPrefs won’t work for me, neither will any other in-unity saving type. Also, I’m using C#.

Without IO i think file can’t be access . Try scriptable object if work for you.

I figured it out.

        saves = new StreamReader((System.IO.Directory.GetCurrentDirectory()) + "/saves.txt");
		realsaves = (saves.ReadToEnd());
