GCF (Assumed to stand for Game Cache File) files can best be compared to a virtual file system not unlike FAT or other common file systems.
The virtual file system supports meta data, file fragments, checksums and other minor features.
This is a useful technique because it means GCFScape doesn't have to read tons of data into memory to read a GCF file and it can read a GCF file without having to seek all over the place.
