KB10347 - Why is my registration/world file (TFW like), created with another GIS software product, not visible in the DK?

Some software products assign crazy dates (such as thirty years in the future) to world files during rectification, which the Borland code (for some reason) in the DK then does not accept. Check if your TFW (JGW, etc.) file has a logical date. If not, change the date to something reasonable, and try again to open the file in the DK (or AIC).
