For a long time I was using Windows Live Sync to synchronize a few folders between my MacBook & MacBook Pro, however it no longer seems to work in Snow Leopard.
I was also using Dropbox to create a shared folder although I wasn’t really using it as a synchronization tool. Dropbox only lets you share a single folder rather than selecting any folders you want to synchronize.
What I didn’t realize is that you can put a symbolic link to another folder inside your dropbox folder to synchronize it. A finder alias will NOT work; you have to use the command ‘ln -s’ in the terminal to create a symbolic link. Thanks to that little known feature, I’m able to use it to synchronize my entire documents folder, my source code, and several other folders.
Dropbox rocks my world! Those guys rock!
