One problem is that external drive has 5 to 10 separate Incremental Backup photo files downloaded from Organizer representing periodic backups. When I experimented to see how Restore would work, it seemed as if I wouldn't be able to download more than one of those files at a time. Holding down one mouse button on a file and clicking on Control or Shift didn't highlight more than the original highlighted file at a time. In addition, it seems that I have a file called "File History," which, when I click it and click it, winds up with a subfile entitled "Pictures," which contains about 3500 jpg photos.
