Hi Louise, first thing you need to do is create a gedcom. this will then be a small file that you can easily copy..........just drag to the memory stick. as regards all the other trees etc, i suggest that you do the same thing with each of them...... although i would suggest that once you have them saved as gedcoms, that they are all merged into one tree, and again..save this also. if needsbe........contact me offline........0161 796 3252 and i'll discuss things with you. regards Josev
