I am using Elements V7. How can I import photos off my camera or card without duplicating the photos I previously downloaded? I know if I deleted the files from the card the duplication would not occur, but is there another way?
By default, Photoshop Elements should not import duplicate files from your camera. Duplicates should not even be listed in the Adobe Photo Downloader dialog unless you have the "Show Duplicates" (at the top, under your device list, next to Show) option enabled. Even if you enable Show Duplicates, all duplicate files will be unchecked.
However, it is possible that changes made to image file on the computer may make the Organizer not believe the file is a duplicate. The Organizer looks at the file's name, size, and modified date. If a file is imported and some of this information is changed, it may no longer be matched up with the original file.
