Authorize an application to use an existing folder

Question

Using the Android Drive API when trying to connect using:

mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Drive.API).addScope(Drive.SCOPE_FILE)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this).build();

getGoogleApiClient.connect();

I get an account selection screen and after choosing an account I see the following:

View and manage your Google Drive files that you have opened or created with this application

What if I access files created by other applications?

Is there a way for my application to request authorization for a specific folder?
