DGC is the extension given to files created by a compressed archive tool called DGCA (DigitalGCodecArchiver). DGC is a compressed archive format in which the program saves the created files. DGC files have a good compression ratio, which is usually higher than in the case of ZIP archives.

DigitalGCodecArchiver is a Windows program by Shin-ichi Tsuruta. DGC files can be found when distributing games based on the MUGEN engine.
