Because of limited space on teh system drive, I stored the pictures on a memory card which Organizer sees as an external drive. Apparently the backup function does not backup photos on an external drive. My goal is to move the catalog to a new computer. Any suggestions?
From my experience, you can't backup files stored on a memory card or USB stick, only files stored in conventional drives, external or internal. No problem with files on conventional external drives. Storing on memory cards or sticks is limited in size and reliability. USB external drives are big and cheap. I recommend to use the 'move' command or the drag and drop function in the folders panel of the organizer to move your library from the card to a conventional drive.
