# Shapefile

Esri shapefiles are a simple, non-topological format for storing the geometric location and attribute information of geographic features. A shapefile is one of the spatial data formats that you can work with in ArcGIS.

The shapefile format defines the geometry and attributes of geographically referenced features in as many as five files with specific file extensions that should be stored in the same project workspace. The file extensions are as follows:

`.shp`: The file that stores the feature geometry.

`.shx`: The file that stores the index of the feature geometry.

`.dbf`: The dBASE file that stores the attribute information of features.\
\&#xNAN;*When a shapefile is added as a theme to a view, this file is displayed as a feature table.*

`.sbn` and `.sbx`: The files that store the spatial index of the features.\
\&#xNAN;*These two files only exist if you perform theme-on-theme selection, spatial joins or create an index on a theme's SHAPE field.*

`.prj`**:** The file that stores the projection information.
