GSP is now Avanquest Software, but the family tree programs they sell are produced by other software houses.

Although you can copy the data files to your laptop, you will need the original software program to read it. I had a copy of the program about ten years ago but have lost the disc. When I was having problems with my 'C' hard drive, I copied the GSP data and program over to a laptop via USB before re-transferring it back again to a new hard drive, but although the data is there the program won't work on either the laptop or desktop. I eventually managed to rescue ten years of research by importing the data to Family Tree maker instead.
