Nope. I'm using Godot Engine, and actually the path I tell the engine to save the file to is this: "user://". The engine then uses that path based on the device/platform the player is on to put it in the correct folder. That folder is the same for Godot 4 as it was for Godot 3, which is the engine version the last LORED version used.
That also explains why idk where it saves the file to for HTML, because all I know is "user://"
