Following are few extensions of shapefile;
- .fbn and .fbx—The files that store the spatial index of the features for shapefiles that are read-only.
- .ain and .aih—The files that store the attribute index of the active fields in a table or a theme's attribute table.
My questions are;
1) When would .fbn and .fbx files will be created in shapefile? What are read only features of shapefile?
2) When would .ain and .aih files will be created in shapefile?
Any help is highly appreciated.
