 rres file format consists of a file header (`rresFileHeader`) followed by a number of resource chunks (`rresResourceChunk`). Every resource chunk has a resource info header (`rresResourceChunkInfo`) that includes a `FOURCC` data type code and resource data information. The resource data (`rresResourceChunkData`) contains a small set of properties to identify data, depending on the type and could contain some additional data at the end.
