My computer has directories that I'd like to share with some friends. I'd like them to have the option to see the file info and decide which files they would like to receive. Who needs the Pro version? Does my source compute need the Pro license, or does each friend's (receiving) computer need a Pro license? If the receiving computers need the pro licenses, what happens when their free trial expires? Do all the files suddenly start copying to their computers? If the receiving computers need the pro licenses, do the users have time to set "Sync All" to Off before the file transfers start? Sorry to have to ask these questions. My free trial expired before I was able to get my friends to start using Sync. Thank you, Jim
