I've been using Synk. It is $45/60 depending on what version you purchase. And a little less to upgrade. I have the Standard version and am thinking about upgrading to Synk v7, however, I don't really need to at this point and I'm wondering what do you all use? Most important features for me: 1. Foward, backward, or pure synch between two master folders. 2. Deletion synch 3. Omitting certain files from being synched. And maybe it's a tradeoff between price and features, but who knows. My perspective is that $60 for a file synch program is on the steep side. Thanks!
