Try this when you search for the path:

return (Application.persistentDataPath +$"\{directory}\{fileName}");

You might need to combine the path though. Here’s an example on how to do that:

var path = Path.Combine(Application.persistentDataPath, $"\{directory}\{filename}");

For some reason Unity threw a fit about the $, but I caught the 1 line in the tutorial I missed (my bad) that created the directory if the directory was missing. Thanks anyways though :slight_smile:
