Application.persistentDataPath is a string property in Unity that gets the path to a directory where you can store data that should persist between sessions. This directory is not cleared except by deleting the app itself. It is safe to use this directory for saving game states, settings, user profiles, etc.
The location of
persistentDataPath varies depending on the platform:
<Application_Home>/Documents. This is backed up by iTunes and iCloud.
/storage/emulated/0/Android/data/<packagename>/files which is a private folder accessible only to the app. It is deleted when the user uninstalls the app.
Here is an example of how you might access and use
Application.persistentDataPath in your code:
In this example, we're combining
Application.persistentDataPath with a filename to create a full path to a text file. We then have functions to save data to this file and to load data from it. This approach ensures that the data persists across game sessions and even after the application restarts.
