I have a Gaming Desktop with Windows 7 and a (new i7) MacBook Pro that works great. I'm tired of updating my pictures, music, and other folders manually between my desktop and macbook pro. I want both of them to automatically update and sync with each other through LAN (not internet). For example, let's say I go out with my macbook pro and I save this awesome picture in my 'Pictures' folder in OSX. Once I get home, I open 'some program I'm asking for' to check my Pictures folder on OSX and "My Pictures" folder on Windows. What this program will do is check both folders and copy whatever picture is missing... so basically the folders will be replicated and updated automatically. Does this exist? It would really help because I'm sick of manually updating my files between my desktop and laptop. I know there are other methods but I find this the best for me.
