.DIV File Extension
What is a DIV file?
Project file created with DIVA-GIS, a mapping and geographic data analysis program; includes a map image and a collection of layers used to display objects and properties on the map; also stores parameters that describes the map’s scale and center.
DIVA-GIS Project files can be created by selecting Project → New within the application. Objects can be added to the map by selecting Layer → Add.
NOTE: While DIV files include layers, the layer data is stored in separate files. These files are often saved with a .SHP extension in another directory. Since layers are saved separately from projects, when a project file is deleted, the layer data is still available.
