I would like to split a single shapefile into multiple shapefiles by using unique values for one attribute/field to select features for each value out into a new feature class.

I found ET Geowizard to do this but it's not free.

In arcscripts.esri.com I found a tool named "SplitLayerByAttributes" but it does not work in ArcMap . (see comments below, this was an old version which has been updated. The new version can be found at resources.arcgis.com )

Do you know of any tools or solution to split by attribute in the way described above?
