I have a similar combination, except one is a laptop which I take on trips. It works fine, as long as you always update the master after making any changes on one computer, and update the other computer from the master before working on the same
file there.
Since there is no possibility of the same file being open on both machines, I have started to look at cloud syncing, since the SyncToy is no longer being supported. DropBox seems to be the most efficient as it only updates changes. Just verify
the synchronization is complete on both machines.
