The 4th byte in the SWF file carries the version number, for example 0A is for Flash Player 10.
EDIT: Because of the high interest this question got I’ve decided to give more feedback
The first 8 bytes of any SWF file are not compressed, the rest of the file could be compressed (or not) by zlib compression.
