@gopherchucks ,
BlueHarvest is useful to not litter CIFS ("Windows") network shares with ._files (I use it exactly only for this purpose). This is often a requirement in office networks.

BTW you are right in advising that removing indiscriminately the ._files could have adverse effects; sometimes resource forks contain useful data.

So, in a nutshell, it's better to use this software only if one knows what he's doing...
