Studio 14 & 15 introduces the ability to set a folder as a Favorite. If a folder on an external hard drive is set as a favorite it is possible that you will lose that folder as a Favorite if the hard drive is disconnected or turned off before launching Studio. If this issue occurs, you will have to reselect that folder as a Favorite. It is recommended to designate a folder as a Favorite only if it is on a local hard drive.
