Thank you so much, I have worked it out, that didn't quite work on my laptop but knowing that the file was called myplaces.kml I was able to find it and copy it over, I am so pleased.
Thanks again for your help!
You know you are a geocacher when......you buy a new laptop and all you are worried about is losing the plots you have in google earth......
I backed everything up on an external hard drive and have everything else like music, photos etc., but I can't find a way of getting the google earth pins/plots over to the new laptop.
Am wondering whether anyone knows how to copy them over? They must be saved somewhere but I can't work out where.
