What is an SD7 file?
Content package created for the Spring engine, a real-time strategy (RTS) game engine; contains game files stored together in a compressed .7Z format; can contain maps, graphics, AI scripts (.LUA files), and other game content.
NOTE: The Spring engine also uses .SDZ files, which store the package as a .ZIP file instead of a 7Z file.
