A shapefile ZIP file is a compressed archive that contains a set of files that define the geographic features of a map. These files include: .shp: The main file that stores the geometric shapes of the features, such as points, lines, and polygons.   .shx: An index file that helps ArcGIS Pro quickly find the features in the .shp file.   .dbf: A database file that stores the attributes of the features, such as their names, addresses, and other information.   .prj: A projection file that defines the coordinate system of the map.   .xml: (Optional) An XML file that stores additional metadata about the shapefile.
