Does this option only upload photos and videos in the folders selected under "choose folders", or does it also upload what are in different folders? Also, does it prevent said photos and videos from being uploaded to the normal Google Drive?
- "Google Photos - Learn more" goes to https://support.google.com/photos/answer/6156103 which explains how to link Google Drive to Google Photos and vice versa.
- "Photo settings" goes to https://photos.google.com/settings, which offers one of the options mentioned in "Learn More". This option is called "Google Drive - Sync photos & videos from Google Drive". It's a yes/no question without any "which items".
Both links don't mention Backup and Sync. If you enable the options to link Google Photos and Google Drive, those options work regardless if you even have Backup and Sync or not.
