Store Application-Specific Data in Google Drive
Fleeting- Référence externe : https://developers.google.com/drive/api/guides/appdata
application data folder is a special hidden folder that your app can use to store application-specific data, such as configuration files. The application data folder is automatically created when you attempt to create a file in it. Use this folder to store any files that the user shouldn’t directly interact with. This folder is only accessible by your application and its contents are hidden from the user and from other Drive apps.
The application data folder is deleted when a user uninstalls your app from their MyDrive. Users can also delete your app’s data folder manually.
