Rather than move ExtraPackages/Enhancements from my separate AddOns directory (outside the $TopDirectory tree), I appended ExtraPackages to $Path by an AppendTo statement in ToFileName[{$BaseDirectory, "Kernel"}, "init.m"]. Note that I used the Windows system variable MATHEMATICA_BASE to point to that separate AddOns directory. (I did not also set MATHEMATICA_USERBASE to point there, since that has the unpleasant side effect of the names of all my pallettes in that separate AddOns directory appear twice on the Mathematica File > Palettes menu!)
