Shipdata.scf I believe in the default installled version of the game, patched, with no mods is 0 bytes in size.. IE.. it is storing nothing.. however if you save a game configuration of a ship, I believe that the game uses this file to load personal ship settings (saved ships).. even though the saved ships are in an editable list much like the Core and Default files,, the Shipdata.sfc is that the game uses to load the settings in those files.. IE: I think it records the ship save meta data...
