FAQ: Why does ArcToolBox's MIF to Shapefile tool create a new column in the shapefile?

Question

Why does ArcToolBox's MIF to Shapefile tool create a new column in the shapefile?

Answer

The MIF to Shape tool adds an item named [shape_file]_ID to the shapefile attribute table. This new item contains a record pointer back to the .MID file. The MID stores the MapInfo interchange file's tabular data. If the shape is converted to a coverage, this field is used as the coverage ID field.
