=== Notes and Comments === 

* SWF file format has been created by [https://en.wikipedia.org/wiki/FutureWave_Software FutureWave Software]. In December 1996, [https://en.wikipedia.org/wiki/Macromedia Macromedia] acquired the company. In 2005, [https://en.wikipedia.org/wiki/Adobe_Inc. Adobe] purchased Macromedia and format has been rebranded. <br>Read more about history on [https://en.wikipedia.org/wiki/SWF SWF wikipedia article].
* Files can be compressed with '''ZLIB''' compression (CWS signature) or with '''LZMA''' compression (ZWS signature).
* [https://en.wikipedia.org/wiki/Scaleform_GFx Scaleform GFX] files share the same file format with the SWF Flash files.
* SWF is acronym for "'''Small Web Format'''" and it was designed to eliminate confusion with a different technology, '''Shockwave''', from which SWF derived.
* SWF file is typically a compiled version of '''FLA''' file (Macromedia Flash Project File)
* Unreal Engine 3 uses containers for GFX files with [[Unreal Engine SWFMOVIE|SWFMOVIE]] extension.
