I am a bit like William. I want to sync my business office desktop with my home office desktop and with my laptop. All I want is that when the contents of a particular folder are modified on one computer, that the same folder is updated on the other two computers. I have Sync installed, but I don't know that it is working. Does Sync work continuously in the background or only when the sync function is activated? Or should I be looking at FreeFileSync? Thank you.
