What are DGC files and how to open them

What is a DGC file?

A .DGC file is a DGCA Digital G Codec Archiver file.

Digital G Codec Archiver format is a compressed archive type developed by Shin-ichi Tsuruta in 2001. It is a freeware utility intended for collecting one or more files or folders and compressing them into a single file that offers better compression ratios than ZIP. Its chief purpose is archiving and compressing data while maintaining support for Japanese filenames via Unicode.

The format is written and read by the DGCA (DigitalGCodecArchiver) application on Windows. Files created using this tool bundle content in compressed form, so they must be decompressed by DGCA itself. DGCA was designed as the successor to the earlier GCA archiver, improving compression efficiency, providing stronger encryption, and better support for Unicode filenames. It has seen niche use in distributing character or asset files for M.U.G.E.N-engine games.

Datasets in this format begin with a four-byte ASCII signature "DGCA" at offset 0, followed by another ASCII string "DATA" at offset 32. These byte signatures serve as identifiers that a file is in this format.
