What is the file format of a SHAPE file and what files do I need?
The required files from SHAPE are .SHP, .SHX and a .DBF files. All files must have the same name. Other files are sometimes supplied but are not necessary (they will not cause a conflict). SHAPE files are a specific file created by ESRI and have become the de-facto standard in most GIS applications. Shape files can be read directly on the G4 as a background file or converted to Job files to make interactive.
