blender game engine how to pack a file blend

You can only pack certain types of files into a single blend file. For example, textures can be packed into a blend file. Sound files that you use via the sound actuator can also be packed, if I recall correctly. However, external blend files can’t be packed into another blend file.

EDIT: Oh, and a simple method to do this is to go to the File menu, then select the External Data menu, and from there, select “Pack into .blend file”.
