Spatial Import
Spatial Import is a Windows command-line utility used to translate .SHP, TAB, .MIF/.MID, and .DBF files to a Centrus database (.GSB) file. It can be downloaded from the Spectrum Spatial section of the Welcome Page, under Spatial Import on the Utilities tab. Once you download the zip file, you have the option of using the either the 32-bit (x86) or 64-bit (x64) version. See Spatial Module Conversion Utility for more information on using this utility.
