I have 2 laptops and I want to sync certain folders on those laptops via an external hard drive. For example: my music folder. I want it backed up on the external hard drive, but for each laptop to have a local copy too, and I want each laptop updated once one of the laptops makes a change to the folder and I connect the other laptop to the hard drive.
Are there any free programs that can help me do this?
I run Windows 7.
