Notes and Comments
- Files can be compressed with ZLIB compression (CWS signature) or with LZMA compression (ZWS signature).
- Scaleform GFX files share file format with the SWF Flash movies.
- SWF is acronym for "Small Web Format" and it was designed to eliminate confusion with a different technology, Shockwave, from which SWF derived.
