I have two computers with windows 7, one in my home town and one in another town. So they are not in private network but I have internet on both. They have exactly the same file structure. I am searching for program that can keep the data equal. I know about dropbox or google drive but they are cloud and I don't want to use them. Also they are using folder that you should copy your data in it. There is another programs that are like a server, just put something and after that you can download it but I dont need them. I want just to point which folders to be synchronized and the program make the synchronization. The sync can be in real time if the two computers are powered, or after few time when they are powered. Or it can lock another computer synced folder till update is required. At all this is my documents that I want to be synced in all my computers and to be changed from where I want. In fact I can move the updates with flash but if some program save the changes and make them on another computer with one click it will facilitate my work.
