With all do respect to @xarx’s contribution (which was very well executed, no qualms there), why I didn’t want this feature in the first place: This creates problems: Windows 10 User Folder Sync, v1.7.0 Attempting to open folders that do not exist and probably more.
Thus my proposal: Make following junctions an advanced config option, disable it by default and discourage using it (like ignore delete thing, which doesn’t prevent people from using it, but at least allows us to give limited support for it). Any disagreements on this @calmh and @AudriusButkevicius?
