The new Service feature allows Windows syncing even when NOT logged on. This feature has been anticipated by BTSync users for years now.
Tested about a year ago and found it to work great.
However, I love the control of having my own 'no-one-elses-drive' and do not want the convenience (or terror) of syncing between devices.
Don't understand your comment. The joy of BitSync is being able to instantly share among your own devices only, without having to use a 3rd party cloud service like DropBox.
I like to carry backups of certain PC files on my smartphone, and for this Sync works sensationally well. The newest version of the software lets me edit files on my smartphone too, and though I'm not sure I want to do that, it is remarkable the number of options one has for managing files across multiple devices (and Users too, a feature I do not presently use). Downside is that it is nontrivial to set up and use; a geek program for sure.
