I have shapefile with next attribute table :

(name of features, unique number for each feature of layer)
I must split shapefile by NAME field, but in result in attribute tables of layers should be only unique number column (see picture):

Split layer by Name I create in QGIS. Is there any solution to delete column "Name" in many shapefiles (about 800)?
I use ArcGIS, QGIS, PostGIS, OGR...
