Psy commando: Re-wordedthe introduction a little. Added mention of instances where the format was wrapped in a SIR0 container. Changed title.

The PKDPX format is used as a compressed container for generic data. Unlike its specialized equivalent the [[pmd2_AT4PX|AT4PX]] format, the PKDPX format can contain any kind of data. The format of whatever is contained will vary depending on context, and what file extension the file that contained the PKDPX contained had.
Its content is compressed using a custom compression format dubbed [[pmd2_PX_Compression|PX Compression]] for the lack of a better name.

== File Structure ==
The structure is very simple. A 20 bytes long header followed with the compressed data.
