Archive labelled GC6, 103 KB, packed as ZIP with no model, brand or revision information in the name. It appears to be the base entry of a GC6 family alongside GC6A and GC6C. The size suggests a boardview, a small schematic extract or a firmware binary. Inspect the contents to determine the type; boardviews open in tools like OpenBoardView or FlexBV, while binaries are written with an SPI programmer after the original chip has been read and saved.
