I'm sure this must have been asked and answered before, but I just can't find it right now...
I have a Visual Studio post-build action that currently does a recursive copy (using xcopy) of an output folder to a different folder. This takes longer than I like and I'd like to only copy newly created and newer (changed) files each time (which xcopy doesn't seem to support).
I cannot depend on any not-installed-by-default tool since the solution is used by different developers on different machines.
What would a superuser do?
