how to prevent overwrite previously created file

Question

I have a game that I have installed from the play store and the application creates a file when it starts. the problem is that when i do an update to the game the old save file gets deleted or overwritten. how can i fix this?

my file code in global script:

var save = {
    "value1": 1,
    "value2": 1,
    "value3": 1,

    }
func _ready():
    load_data()
    save_data()

func save_data():
    var file = File.new()
    file.open("user://save77", file.WRITE_READ)
    file.store_var(save)
    file.close()

func load_data():
    var file = File.new()
    if not file.file_exists("user://save77"):
        return false
    file.open("user://save77", file.READ)
    save = file.get_var()
    file.close()
    return true

You can save it online online or use custom dir that doesn't deleted with app. Learn how to do it here (GitHub/Godot/Issues), EXOMODE's comment contains the answer

func save_data():
    var file = File.new()
    if not file.file_exists("user://save77"):
        file.open("user://save77", file.WRITE_READ)
        file.store_var(save)
        file.close()
