Thanks for your very quick reply! I have been using ArcView/ArcMap since ver 3.0 and this would not be the first time something has seemed to be dropped or omitted. I was trying to get an ArcMap add-in that was written in VB.Net for 10.0 using VS2010 to compile/run in 10.2 using VS2012. Initial porting into the 10.2 environment gave me numerous errors and warnings but I managed to correct them all except for the DataManagementTools. When I could not find this dll etc installed then I went to ESRI as you did and found "empty" pages.... It could have been dropped in 10.1 or just an oversight. Thanks Andrew
