Codecs folder

[FREAK]

hey um
when i bought my NZ90 From ebay the seller didnt send me the orignal disk
but im not really fussed as it didnt make a difference...

so i was browsing the contents of the cd when i came across a folder called codecs

filled with avx #########.prc files

i heard about the ripped vz90 codec but i wasnt sure

i couldnt be borthered to list them all here so a attached an image:

What are they for???
