Spatial file formats are only concerned with the location of objects in space (i.e., their coordinates) and not with their attributes (such as line or fill style, marker symbol used, text labels, etc.). Boundary files such as [.BNA] and [.GSB] are spatial formats. Some other formats, such as [.DXF], can be exported as a spatial format even though the file type is not strictly a spatial format (Use only spatial information option).
