What is an SGA file?
Game archive file used by Relic Entertainment games such as WarHammer 40,000: Dawn of War (DoW), Company of Heroes (CoH), and WarHammer 40,000: Dawn of War II (DoW2); used for game assets and may contain various types of files, including maps, graphics, game scripts (.LUA files), audio (.FDA files), and game unit information.
Corsix's Mod Studio and Mod Studio 2 are common tools used for modifying SGA archives. Mod Studio 2 includes a program named SGA Reader 2, which can unpack SGA files for editing.
There are multiple versions of the SGA format. Therefore, an archive used by one Relic game may not be compatible with another game. An example utility that converts version 4 archives to version 5 archives is sga4to5.exe.
