Window’s Live Sync Service , Free from Microsoft

Windows Live Sync service. It is a good and free Window Live service for Windows and Mac.

Problem: We have a home machine and work machine or laptop or desktop PC which is out of house frequently or small business.

In the case when you want to copy important records after each trip: you come back home with the laptop, you move to office after completing the work at home in the weekend, so on.

Solution: You have allocated one folder on the Computer A and other folder on the Computer B. The Sync service will magically keep them synced in the internet without any effort from your side.

 Just change, add or delete on the laptop; we can find it changed, added or deleted in the desktop.

Edit various spreadsheets or chapters on the Mac at house then we can find it edited in the same way.   

Plenty of such services are available in online
