I keep my laptop computers (3 that I use for different purposes but all have the same data on them) and my desktop computers (2 in different locations in the house) synced with my NAS servers for my data and backup. If it isn't sure which file is the latest (because of minor differences in the time stamp) it will not sync until you tell the program which you want to keep. I have used the Pro version (2 licenses) on my two most active computers (there is a nag statement if you transfer more than about 40,000 files in a month without the pro version) and the free version on the remainder of the computers for about the last 5 months and have never had any problem with the program at all. This was one of my best purchases ever for a great little utility program. I have no financial or other connection to the company other than a user.
