I think everybody knows the image viewer irfan view…
I ask irfan, if he could implement the formats rpf and rla. this would be great. he doesn’t know the formats and asked me if there are informations about the formats, I think like papers or so…?! does anybody know more than me?
As far as I know, in the 3dsmax SDK you will find the source code for the 3dsmax .rpf and .rla IO plugins. (I’m not sure if this would create any copyright issues though.)
