Notes about the GDW file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The GDW file type is primarily associated with 'GedStar Pro' by GHCS Software. GedStar Pro is an addition to the line of GedStar PalmOS genealogy programs. It is optimized for the devices with color screens, fast processors, and increased storage space. This file type contains conversion settings for the genealogy database.
