Create copies of original images automatically when you first save them

Reopen the original image
In the Open dialog box or the Navigation palette to browse to the Corel Auto-Preserve subfolder that contains a copy of the original image. The Corel Auto-Preserve subfolder resides within the same folder in which original image was first saved.
