We have myheritage on our home PC as well as on our little lap top (10"). We do most of the work at home, but take the laptop when travelling/researching.
Can someone please tell us the easiest way to update our files between the two computers. We dont want to have to type in the new info on both, neither do we want to delete a tree and reload a new one. Do we need to save / back up / export gedcom?
Due to the fact that your family tree file is saved locally on one computer, it does mean you will have to transfer that file to the other computer every time you want to work on the tree.
There isn't a way to work on a tree simultaneously on two computers and then synchronize the information between the two of them. (it's possible to merge two gedcom files, but duplicate individuals will not be recognized so you'll end up with a mess if you try to merge two copies of the same tree)
There is, however, an easy way to transfer the family tree file together with the photos so that you can transfer it without hassle to different computers.
In Family Tree Builder go to the File > Back up project menu. Use this feature to create a backup of your tree.
Copy this file to a pen drive or other removable media device and transfer to the second computer.
Open Family Tree Builder on the second computer and go to the File > Restore project menu. Use this feature to restore the project and continue working.
When you want to transfer the tree back to your first computer repeat the process Back up > transfer to new computer > Restore.
Actually that's not strictly true. If you set your saved location as an external drive (in my case I'm using a removable pen drive), you *are* able to work from the same drive on multiple computers. This is how I'm moving from my desktop computer to a laptop and back again with no problems.
You can get flash drives very cheaply these days, you can get a 1GB stick for about £4 now.
