I'm trying to do exactly the same thing. I want the PC to write all changes, additions, and deletions to the phone. I don't want the phone to be able to affect the PC folder. I've seen this setting mentioned, but I'm unable to find it on either PC or phone: " enabling overwriting of changed files". Where is it?
I'm trying to install Sync as a windows service on Windows 10. Installation appears to go fine, but as soon as I try to add a folder or do much of anything in the web gui, my computer instantly crashes and reboots itself. Any ideas what's wrong?
