intro

TextHeader.bin is created by Binpbo personal edition 2.5 and greater. It is placed in the primary folder of the addon.pbo, and comprises of information from all pax files encountered in that addon from all it's possible data trees.

BIS have finally learned to use relative file addressing. This might be the precursor to a better future where we leave oops modelling nightmares behind.
