Looking for a software solution for File synchronization on two different laptop computers. One is running windows 7 and the other is running Windows vista. Also, the laptops are in two different physical location. At work office and at home office. The amount of data files currently is approx 30GB of data, so not sure online will be best option or not. Could do portable hard drive but have multiple folders to be sync in various locations on computer. Tried looking at AllSync application but it seems to only sync to one folder at a time and need to be able to set up multiple folders. Also looked at dropbox.
