the drive.file scope is restricting the scope of the app to only the files created or opened by the app but the files shared or added to the folder created by app is not accessible, Whereas drive as a scope gives the full access to the entire drive of the user and which is the restricted scope.
Is there any middle way between these scope to access the file inside the folder created by the app?.
If not then may be Google should think on it because in either of the way user have to comprise either on the privacy or on the functionality.
