I'm trying to find out the format for .cpt files that are produced with Corel Photo Paint so I can extract a thumbnail bitmap from these files. Windows can do it, as it displays Corel's .cpt files as thumbnail icons in Windows Explorer, so I assume it's not proprietary information. The version I'm working with is Corel Photo Paint 8. Google's no help as it only lists 3rd party software. Anyone have a clue where to look ???
