.SBX File Extension

File used by ESRI ArcGIS Desktop GIS mapping software; contains a spatial index for a .SHP shapefile; used to optimize queries and reduce the overall time spent accessing multidimensional object shape information.

SBX files are optional when specifying a shapefile. However, shapefiles without spatial indexes may suffer from slow loading and rendering times.

Compressed archive created by Shoebox, a tool included with the GLBasic software development toolkit; can store application resources such as graphics, video, music, or data files; can be decompressed by the application at runtime to extract specific files.
