- Description
- The Adobe Flash format, SWF, previously known as Shockwave Flash or Macromedia Shockwave Flash, and alternatively known as the Small Web Format, is a file format primarily designed for creating interactive multimedia applications. The format iterates rapidly, often in line with new releases of Adobe Flash or Adobe Air. Prior to version 6 all SWF files were uncompressed, however version 6 introduced the option of using zlib compression. Version 13 introduced the option of using LZMA compression.
