Is there an easy way to find out under what name renpy makes directories in the AppData folder, either via a console command in the renpy game, or maybe a 3 party program that can keep track of which directories a program makes ???
Use Unren, open game\options.rpy and go to the line that starts by: define config.save_directory =
Or, via console, type config.save_directory and press Enter.
If you hash tag like this: #define config.save_directory = ""
It won't save to the app folder anymore. It will only save in the game folder. I do that on every RenPy game I play because I don't want duplicate saves.
