no you put the big file inside the data folder, you edit the command line to look something like "C:\Program Files\Sierra\Homeworld2\Bin\Release\Homeworld2.exe" -mod PLANETPACK.BIG,OLDSHIPS.Big,SWSOUND.BIG,SWMUSIC.BIG,GENHODS.BIG,SHIPHODS.BIG,CORE.BIG -luatrace -hardwarecursor You find the command line if you right click the HW2exe on you desktop and press properties, then change the target to what i have here ( i assume you installed hw2 in the default directory), anyways, i hope that helps
